[@lukomatico]

First?! (After the pinned comment anyway hah!) - just coming back to actually comment after watching, - excellent work mate, it's really interesting to see this as a viable option!! Lovely result 👍👍

[@CuivTheLazyGeek]

Woohoo, well done mate! Yeah I'm so happy to see filters and techniques getting this good :)

[@Rotceh-r4g]

22:46 says it all. Joy and enthusiasm in astrophotography! I enjoyed watching it Cuiv!

[@CuivTheLazyGeek]

Thanks so much!

[@JVRost]

Congratulations on the new toys) About a month ago I also became the owner of such filters, only the Askar 6 nm brand. Now my life is hell)) I had to learn Pix)) The kit is not applicable to all objects, but like a child, I re-shoot everything and am happy. The camera is the same as yours, and the GSO telescope is 150/570 mm. It makes it all the more interesting and relevant to see how other owners of such a set of filters process.

[@CuivTheLazyGeek]

That's awesome!!! And good luck with PI :)

[@Apagadorable]

I have been waiting for quite some time for a quality sii/oiii filter and I'm surely not the only one!

[@CuivTheLazyGeek]

This is high quality for sure! The individual reports really sell me on those filters :)

[@captaindanield5827]

Yes the individual reports sold me also. But the cost was too much for the 4nm and I have ordered the 6nm versions. Just back in stock (July 2024) I hope they are good enough. A direct comparison would be interesting.

[@dijonpepperberry]

At the linear state rather than multiplying by 0.1 for your blues, instead consider additive operations. That way you can get 100% of your strongest signal and "add" maybe 10% or 20% of your weaker signal. Linear has so much headroom when stars removed.

[@comeraczy2483]

C'est joli tout plein! Un grand merci. This is a really exciting combination of filters indeed. Thaks for sharing your processing method. The outcome is really awesome. As a very interesting coincidence, James Lamb just published his take on the equivalent (but 5nm) set of Antlia dual band filters. Difficult to get a feeling of how they compare because it's different targets, different skies, and different processing methods.

[@CuivTheLazyGeek]

Merci beaucoup ! I'll have to check James' video! I'm not so hyped about Hb SII, I prefer to simply get OIII twice :)

[@celestromel]

Cuiv, you are a genius! You are reinventing our hobby!

[@davidfabrizio3942]

Yes, but it would be much better if he put out a written procedure. It is very difficult to read the screen and keep up with the fast pace when you're trying to take notes.

[@FrootyRecords]

Incredible result Cuiv!. you are going to make me spend more money again!. aarrrrr! . Seriously though, fantastic results from Tokyo. Loving your content as always. Big ups to Altair too, competing admirably with the other big guns in the filter world..

[@CuivTheLazyGeek]

Hahaha sorry about that!! It's a really good pair of filters :)

[@deep_space_dave]

This puts the fun back into astrophotography! This is how lazy processing should be with no mono required for SHO, love it! Amazing results with so little effort or at least you make it look effortless 🙂 Really appreciated you making a video on how to blend these 2 filters, now my wallet is crying again now that I want a Oiii/SII dual band filter LOL. Clear skies Cuiv!

[@ravnica1]

I would have given you a hint but I cannot undermine my good friend

[@CuivTheLazyGeek]

Hahaha I feel so sorry for your wallet!!

[@josephgiammarco8261]

Same. I can't just drop another $1000 for those two filters. I can't. I really can't. Now, where's my wallet?

[@PhotonNoir]

Thx Cuiv for this great tuto. The idea to mix 2 dual band filters to get Ha, Sii and to combine Oiiis is very interesting. I will probably test it !

[@CuivTheLazyGeek]

Glad it was helpful! Have fun!

[@Bambi851]

Wow, this video just blew my mind. So many new things to try out. Thank you.

[@CuivTheLazyGeek]

Thanks for the feedback, and have fun trying things out :-) 😁

[@davidjennings2733]

Great stuff Cuiv, you accomplished in 10 minutes what would have probably taken me 2 days in processing.. haha, great picture and congratulations on the new filter.

[@CuivTheLazyGeek]

This gives me an idea for a "speed running processing video" :D

[@DSOImager]

Awesome image! I've been advocating for a s2/O3 filter for years.. I even emailed one of the filter manufacturers with the suggestion which was ignored, lol.

[@astroattorney]

Askar has had the ColourMagic D2 out for quite a while now.

[@DSOImager]

@@astroattorney Yep, i know about them. I had emailed optolong shortly after the original l-extreme came out. That was a good bit before askar. To my knowledge, optolong still hasn't put out an s2/o3 filter. A missed opportunity considering the early success/popularity of the l-extreme.

[@CuivTheLazyGeek]

The Colour magic do seem quite interesting! But not quite as narrow a bandpass as I'd like! :-)

[@astroattorney]

Great video! This is an enormous help for me in processing the Askar Super Duo-NarrowbandD1 & D2. You make it look so simple. 😄

[@CuivTheLazyGeek]

Glad it was helpful!

[@abmscopes]

Fantastic thanks! Finally getting 'professional' looking results thanks to this. The only thing I change - and I know many will disagree- is that I only do the noise and blur X's at the very last stage before recombining with the stars. I consistently find that if I do the X's too early in the process, I get blotchy results. In my head it's because 'gaps' where noise has been removed and areas have been sharpened, get exaggerated by stretches and colour balance changes later in the process. In fact I even use the X's on old data processed in other programs years ago and it gives great results there too. Definitely a late stage process for me but happy to have my mind changed!

[@willowen4536]

You always produce a stunning image, but I think this is your best yet, stunning 🤩 🌌

[@CuivTheLazyGeek]

Wow, thank you!

[@TheCynical0ptimist]

This is a great companion video for your most recent Askar "ColourMagic" filter review!

[@lavers_1]

Wow that is impressive Cuiv. What a great image!

[@aethyr1388]

awesome! always great content Cuiv! Thanks for the tutorial as well!

[@CuivTheLazyGeek]

Glad you liked it!

[@domino089]

Great result Cuiv! Love your quick edits that I can quickly get new techniques/scripts from. I was hesitating to purchase Pixinsight for more than two years, but I finally pulled the trigger a few weeks ago and I absolutely love it. Sure, Photoshop works well, but Pixinsight is just perfect for astrophotography, a must have tool.

[@CuivTheLazyGeek]

Congrats on getting and getting used to PI!

[@abmscopes]

One thing I've found with the Oiii signal is that it is very susceptible to being wiped out by the 'remove green' process and also the background extraction. BE especially often treats it as noise, so I like that in Graxpert standalone (not the Pix integrated version) you can play with different settings and see what it has removed so ensure that no precious OIII is wiped! Oh and these days I almost never use flat calibration frames. I just keep things very clean to avoid dust donuts. Again, I find that the use of flats often removes the good along with the bad. But that may be more down to my poor flat acquisition than anything else, but either way I don't feel that my images suffer from not using flats.

[@jreichle59]

Always enjoy your enthusiasm!! Keep up the great work, always informative.

[@CuivTheLazyGeek]

Thanks!

[@stripes7214]

I loved watching you process this image ! It looks so fun to do and your enthusiasm is quite contagious x)

[@CuivTheLazyGeek]

Thanks so much! 😊

[@SteveJuA]

Awesome work! That was in my head for a month ago that can color CCD shot with Dual Band to be Hubble Palette!? Thanks that made me clear that can do!

[@CuivTheLazyGeek]

And now you have the answer :D

[@ciarancopas3433]

Brilliant video Cuiv. Thanks for your videos I got the HA-OIII and love it. I wanted to get the SII-OIII version but I was unsure how to process so thank you very much. No halo on the witches broom with 10 min subs using 533mc pro f/4.3 with 90mm Triplet +0.8 reducer, bortel 6. I just finished 17.5 hours on the Bubble Nebula processed in Pixlnsight with RC tools and Bills Narrow band scripts and really pleased. I didn't know it was from f/4.8 upward. I thought it worked with all refractors.

[@CuivTheLazyGeek]

Yeah I didn't know either - I think Altair is too conservative here, I'd personally say F4 and slower. Your F4.3 isn't an issue at all! (in my opinion!)

[@ciarancopas3433]

@CuivTheLazyGeek Thank you very much, Cuiv.

[@IamArtimon-ui4co]

Thanks, Cuiv !! Encore une super vidéo, qui donne envie d'acheter ... But compared to other brands, those filters are not so expensive, regarding size & dubble band in 3nm. Thanks for this info. Have fun with your local Hubble like scope ;)

[@CuivTheLazyGeek]

Merci beaucoup ! And I agree, while expensive they're still a great deal with the filter reports, lack of halos, and narrow band passes!

[@KaidenBainAstro]

I have been using this strategy with Svbonys dualband Ha Oiii filter, and Askars D2 Sii Oiii filter. It’s a lot more fun to process SHO images than HOO!

[@CuivTheLazyGeek]

Well done on this strategy! It's indeed a lot of fun!

[@hael8680]

Any halos with those filters?

[@darkrangersinc]

Great video! Have you tried the Askar color magic filters to see the comparisons and since those have been out for a while? The S2 O3 filter really lets the O3 come through on your pelican which is great! Cool to see how effect that style of filter is

[@CuivTheLazyGeek]

I haven't tried the Askar filters, their band passes are twice as wide...

[@dumpydalekobservatory]

That's awesome Cuiv I really do hope they make filters for faster scopes as I'd love one or two for the RASA. I'll be seeing the guys from Altair next month so I'll probably have a chat to them about it.

[@KevinRudd-w8s]

Its called the pelican nebula because in early photographs thats exactly what it looked like. It still does when imaged with relatively short exposures. But with modern astro imaging equipment far more detail is captured which can swamp the outline of the bird. Also if your image, which was much better than than the SHO image I captured in July I might add, was rotated 90° clockwise the pelican form would stand out more.

[@CuivTheLazyGeek]

Thanks for this and for your support! I think I get it now!

[@massibegous7261]

Actually it looks more like a Pterodactyl or Pteranodon

[@KevinRudd-w8s]

@@massibegous7261 Come to think of it, yes it does!

[@epielanonimo]

This filters look very interesting but I think it's hard to beat (price for performance wise) the Idas NB12, which supposedly works from f1.8 up to slow scopes for about 220€ (EU price). The NB12 has the inconvenience of needing a UV/IR cur filter in addition to the NB12, but the Touptec 585 should come with UV/IR glass infront of the sensor. (And Idas has a great reputation)

[@MrWacha]

Correct, all OSC cams from Touptek (Omegon and orher re-brands included) already have UV/IR cut filters.

[@CuivTheLazyGeek]

Yes IDAS is awesome, their filters work great! The 12nm bandpasses though are very large, so I prefer the 4nm bandpasses I have with Altair Astro :-)

[@Xu.123]

Dude, 12nm is so wide.

[@martinleondorta]

Hello Cuiv, another excellent video!!! Finally, for your experience and better performance. What brand of dual filters would you recommend and how many nanometers? The Ascar color Magic, Altair Dual band 6nm or 4nm? I live in the City of Barcelona which could be a Bortle 8/9.. my equipment: APM 130/780 F/6 - ASI2600MC DUO - AM5 Thanks for your good advice in all your excellent videos.

[@calimark7448]

Wow! Thanks Cuiv, great processing vid and some amazing results. Im just starting out with PI and these vids really help me out. Im in Bortel 5-6 and looking for some better results. Thanks again.

[@CuivTheLazyGeek]

Glad this is helpful! You'll soon get the hang of it!

[@rtpman1953]

Nifty way to arrive at SHO. I like it. Great video and thanks for the workflow.

[@CuivTheLazyGeek]

Thanks for the feedback!

[@fazergazer]

I wonder what your band profiles look like. I just received mine and the HA+OIII has a conventional Lorentzian/Gaussian profile both channels, very well centered. The SII+OIII has a very nice square profile which should make it more tolerant of slightly faster optics. As promised the reports are 0.1nm!

[@thomasphennigan]

Cuiv I just caught up with this video and am blown away! Could you please do something like this for us Noobie DSLR users ?

[@RobertKarlBerta]

I do both mono with LRGB plus NB full slate of filters....as well as OSC with NB filters. The one thing which hasn't been discussed much is negatives of OSC which is 1/2 of the resolution and 1/4 the sensitivity of a mono camera due to the 4 components of the color matrix. i lean towards the versatility of the mono option but moving more towards OSC as the technology evolves rapidly with these filters.

[@CuivTheLazyGeek]

It's not as dramatic as the numbers suggest, because a lot more goes into it - this is discussed ad nauseam on Cloudy nights :)

[@AsKyOdA]

Beautiful indeed, thank you for sharing the process

[@CuivTheLazyGeek]

My pleasure 😊

[@peterlaubscher3989]

I have the same camera and F/4 10" Newt - would loave to try this filter!

[@CuivTheLazyGeek]

I'd say go for it if you have the funds! I think Altair is being too honest and too conservative advertising f4.8, but that's my opinion

[@Wheelbeer]

Finally ! Thank you cuiv for this.

[@rafdrone2531]

Hello Cuiv, that's an amazing video with an incredible result!! I followed yor indications but for an HOO image of the Heart and Soul Nebulas which gave me lots of satisfaction. BTW I want to ask you something, when you make an HOO or an SHO image like in this video, do you make also a Linearfit/colorcalibration before starting to remove stars and splitting the channels or you just go through blurxterminator, noisexterminator and DBE and don't do the linearfit/Colorcalibration at all?

[@gerardford1116]

Amazing..... Yes!

[@CuivTheLazyGeek]

Yes!!!

[@808musicman808]

Wow! Just wow! Love your videos! I’d like to apply your techniques!

[@CuivTheLazyGeek]

[@kianev]

Amazing video as always, pleasure to watch. Cuiv, may I ask you if your guide camera is Touptek 290MM? If yes, what is the unity gain for this camera? Thanks!

[@CuivTheLazyGeek]

Yes, it's the Touptek 290MM and I have no idea on the unity gain! Since I just use it for guiding I haven't paid attention to that

[@edroberts5193]

Very interesting video. What spectrometer do you use to verify the filter performance?

[@3dfxvoodoocards6]

Interesting video. One question- A 80 mm APO costs more than a Bresser 127/1200 mm f9.4 achromat (400$). But which one is better for normal observations (not astrophotography)? I guess that because of the much bigger aperture the 127/1200 mm should be better. I don’t know which one to buy. I would really appreciate your opinion :). Unfortunately there are practically no comparison videos on KZbin between an achromat and APO at similar prices. Thank you!

[@mistaskate8715]

Very cool! Not related, but if you're up for it it would be fun to see another shootout again :)

[@florinenescu2837]

Great! But if one buys two expensive dual band filters... why not buying in the first place three good narrowband filters?

[@CuivTheLazyGeek]

Good question! The three ultra narrowband filters (4nm or 3nm) will still typically end up being more expensive, and then you need the more expensive mono camera, and then you need LRGB filters for broadband :) it adds up!

[@ilciauscolodicanguro2756]

Ciao Cuiv Thank you as always for the fantastic work you do! I was wondering if it's worth trying to integrate the Altair Astro SII OIII filter with the L-ultime that I already own. Thanks in advance for your opinion. Andrea.

[@bronco_fv]

Ok, Altair marketing and you Cuiv did a good job. I wanted something better than my l-eXtreme (the Alnitak halo was unbearable 😀). I was considering an IDAS but based on the info in this video I decided to spend my money in Europe rather than Japan.

[@bronco_fv]

Bought the Ha / Oiii btw. SII can wait for a while.

[@CuivTheLazyGeek]

Hope you enjoy it! They're really solid filters

[@bronco_fv]

@@CuivTheLazyGeek I’m wondering what your transmissions are. I got ~91% for Ha and ~96% for Oiii (received my one today 🙌🏻)

[@allenbaylus3378]

would it make more sense to have 3 separate filters over 2 dual band with the overlap or is there some importance that I am missing?

[@michaelwitte6803]

I have a couple of questions about this methodology as its very unique. I shoot mono @ f/4.8 in Brotle 6-7 and to get something like the pelican I need 6-8 hours per channel which takes forever. Thinking of 8"RASA and using my ZWO mono but this method seems to work well. How much integration time for each filter to get a good S/N. I know you are in a high Bortle as well. Also, how do you like the Newt you have any collimation issues? The RASA is very temperamental to tilt and collimation so concerned about moving from a nice Stellarvue to something that needs tweaking to get good stars.

[@CuivTheLazyGeek]

You'll still need the same integration time unfortunately, maybe even more because OSC. Also your current filters may not work great with the RASA (and those Altair filters definitely won't), especially Ha and SII because of bandpass shift! You need preshifted filters with the RASA!

[@nikaxstrophotography]

Thanks so much for this video Cuiv, any halos with these filters? Cheers

[@CuivTheLazyGeek]

Briefly mentioned in the video, but basically no halos, some very soft ones on Vega

[@RobertKarlBerta]

Another topic which I haven't seen covered but wonder if anyone has done some research. Some OSC cameras like my ASI 071 have a mono mode you can switch to which goes to BIN 2 to output a mono image using either 2 or 3 of the 4 color matrix channels. I haven't tested this but seems like an option for those that want to have the capability of mono with their OSC camera without buying another mono camera. I recongize there are some negatives but might be an option for some trying to save some money rather than buying another camera.. I know this would double the pixel size but that might be fine with the appropriate focal length scope.

[@CuivTheLazyGeek]

It's the superpixel approach, very standard - you can also do that (with pretty much any OSC camera raw frames) in post!

[@astroamateur5394]

I saw the video with great expectations waiting to see how my man, Cuiv will combine 2xOiii 😊. I think that this is the elephant in the room… After using two dual narrowband filters with OSC, I ended up totally discarding noisy OIII most of the times because I couldn’t raise signal to noise by combining good Oiii with bad Oiii (which was usually the case ) no mater what method I used (pixel math, image integration, I even thought to do batch subframe Oiii integration from the two filters etc etc) … It would be fantastic if an astrophotographer with Cuiv’s great experience (and my favorite KZbinr) experiment on this topic and make some suggestions in a future video. (P.S. I believe that best approach is that a dual narrow band Ha-Oiii and a trusty dedicated SII is the way to go… or not..?) P.S. I use L extreme and hutech Ha-SII) Clear Skies!

[@ronlundgren4391]

Great info, thank you.

[@CuivTheLazyGeek]

Any experience with NINA's plugin for optimum exposure calculator? It always seems to be way too small for me.

[@ssrattus]

Thanks!

[@robertarkins533]

Excellent result Cuiv! I have the Askar Colour Magic version. Any thoughts on using ImageIntegration to combine the two G and two B channels from both filters into Oiii?

[@CuivTheLazyGeek]

ImageIntegration should perform a similar operation as PixelMath, so why not? But I think Pixel math is simply faster

[@jimwaters304]

I would like to see a filter set for OSC that cover SII, Ha, OIII and Hb. Filter 1 Ha + OIII. Filter 2 SII + Hb.

[@CuivTheLazyGeek]

I think Antlia has that - I personally am not a fan of getting Hb. As far as I can tell it doesn't really bring anything to the table, being a higher energy transition for hydrogen. Hb signal will be weaker than Ha signal, and they overlap, as any Hb source will always also be an Ha source (the opposite not being necessarily true), meaning that you've already captured everything Hb has to offer by capturing the much stronger Ha...

[@chessymajewski9669]

Hi Cuiv, do you think my optolong L-extreme would be ok incorporating with Atair Oiii Sii ultra filter? Great video.

[@CuivTheLazyGeek]

Should work fine!

[@goldandsilveruk3268]

I wonder if you could replace the HA filter with something like the Optolong l-ultimate/l-extreme as many have a dual filter already?

[@CuivTheLazyGeek]

That would work perfectly fine as well :-)

[@ciskje71]

It is possibile to use only a single and a dual band filter? (Ha, SII+OIII)? (please please please use also the new Siril 1.2.0 and the new AstroSharp versions!)

[@CuivTheLazyGeek]

Should work as well, just make sure to get only the red channel for Ha!

[@romaindechamps457]

One question Cuiv, giving the lower data from the SII channel wouldn't be interesting yo use bin2 on this session to increase SNR ? What are your thoughts on this?

[@CuivTheLazyGeek]

I'm not a big fan of OSC binning to be honest... Plus it's CMOS binning, so I'd likely prefer to do some integer resample in post rather than do irreversible binning in camera

[@ravnica1]

Dear Cuiv do I have to do it in 2 nights, can I use both filters during one night ? 😁

[@CuivTheLazyGeek]

Hahaha one night works!

[@billmurphypenguins3774]

I like how Cuiv can scrutinise these filters through his expertise, hopefully makes the manufacturers think twice about sending you crap. And doubling up on the OIII integration can only be a good thing. All hail the lazy geek.....

[@CuivTheLazyGeek]

Thank you :)

[@allenbaylus3378]

question - I have an Optolong L-eXtreme Filter which as H-alpha at 656nm and a second 7nm passband centered on OIII near 501nm. It was not cheap (I got it used). Would you suggest pairing this with the Altair Astro SII OIII to gather the SII data and hopefully be able to reconstruct the images as you did with the Altair Astro SII OIII and Altair Astro Ha OIII or do you think that the specs between the Altair and Optolong are too dissimilar to be able to use? The Altair is an expensive filter to add in and doubly so if you end up getting both filters.

[@CuivTheLazyGeek]

It should work - you'll need to judiciously combine the OIII from the L-eXtreme (which should be noisier, although some Ha makes its way in there, counteracting that) and the Altair! You can also check the Askar Color Magic filters - not sure how good they are, but they do have SII OIII as well

[@jeffbrennan5394]

Just purchased my first monochrome camera and it should arrive soon. Should I send it back and get these filters instead?

[@CuivTheLazyGeek]

Monochrome is still the king, the gap is just closing :) if you have mono camera plus individual SHO filters, that works great!

[@realmcerono]

Maybe you can get a coupon for the European Version of the Touptek aswell, called Omegon. Insane result Cuiv. I wonder what happens if you wouldn't throw away any Blue Signal at all. Mathematically there is no reason too to cut the Green - 0.1 + 0.9 will not be better than 0.1 + 1.0.

[@davidfabrizio3942]

At the beginning when the two images are opened, is that after they have been combined, calibrated, etc? He doesn't say.

[@CuivTheLazyGeek]

Just the stacked frames (and therefore calibrated)

[@charliemiller3884]

Why not just use an Ha filter and the SII / OIII dual narrow band for similar results? Also, let's put a filter wheel on that OSC camera to have LUM and the two NB filters and a dark frame filter always available.

[@CuivTheLazyGeek]

To get more OIII SNR and keep all the pixels of the camera busy? And yeah I should be considering a filter wheel

[@samshornvibes]

So when are they releasing a tri band filter woth Ha, OIII, and Sulfer?

[@CuivTheLazyGeek]

It already exists, but doesn't allow doing SHO palette! Because then SII gets merged into Ha, you can't get them separately. I personally don't quite see the points of such filters, as you're effectively decreasing the SNR of your red channel

[@astrophotographythewrightw9364]

super video cheers👌

[@CuivTheLazyGeek]

Thank you! Cheers!

[@KevinRudd-w8s]

Hi Cuiv, re the price, if you compare the cost of the two of them with a set of three filters of similar bandwidth for use with a mono camera they are not that different.

[@HeadbuttWarlock]

This isn't a bad option for someone like me who only has an OSC camera, though! When I have a thousand bucks to throw at this hobby again I'll consider this.

[@CuivTheLazyGeek]

That's very true! Especially when considering the personalized reports!

[@rawhead909]

I'm assuming I could just use the SII/OIII filter with my L-Ultimate (3nm Ha/OIII) in the same manner?

[@CuivTheLazyGeek]

Yes, it shouldn't be an issue, as long as you focus well for each

[@JK-gn9qi]

Is this also possible when you already have a 7nm ha and oiii and add it with 4nm sii and oiii?

[@CuivTheLazyGeek]

Sure it would work! Just combining the whole OIII needs to be done judiciously, looking at how well the 7nm OIII performed!

Méchant, méchant Cuiv. Signé: le portefeuille d'Adrien 😂

[@CuivTheLazyGeek]

Mwahahah, le pauvre portefeuille va maigrir :p blague à part ils sont excellents ces filtres

[@B-Mike]

Hi Cuiv! What kind of knowledge is required to gain undying all the things you are talking about filters/bands/spectroscopy etc. From wayvarious Astrophotography videos, it seems that it is not just pointing a telescope and start shooting pictures. Can you or someone watching/reading my comment to please guide me to various books/sources etc to gain the physics of astrophotography. Thanks

[@marcusa3177]

So in theory, given how beefy the AM5 is you can do a double-barrel setup (same scope, same everything) with each filter getting their own scope? HMMMMMM that would be the ultimate lazy setup, 33% less work (and gear and cost!) vs a comparable mono setup (ie three scopes). The challenge is ensuring that both cameras are roughtly aligned, so you might need a rotator just to confirm you don't end up with perpendicular cameras. Oh, and a LOT of hard drive space. And given you already know the quirks of your newt, in theory the second time setting one up would be easier?

[@CuivTheLazyGeek]

And same angle for diffraction spikes and synchronized dithering and... yeah no too complex for me lol

[@LjubomirDjurisic]

Would it be cheaper if some manufacturer produce SHO camera? Yeah, maybe not, 'cause it will be much less filter to buy and review.

[@keithparker9852]

You should submit that to NASA's APOD. Nice job!

[@CuivTheLazyGeek]

Thank you! Always am too lazy to submit to APOD or the like (I kind of don't really care, if that makes sense)

[@martymiller9802]

I’m trying to figure out your accent. Swiss, Canadian, French?

[@CuivTheLazyGeek]

French!

[@martymiller9802]

I am a physicist who spent 17 years in Geneva et he suits bilangue. I have several colleagues with a similar accent. I’m following along your presentations. I may try to setup a Nikon CoolPix 950 to fix on the sky. It’s fascinating.

[@martymiller9802]

Autocorrupt got me.

[@Alan-vk6bk]

I can see the appeal of these filters but £400 for each is a bit expensive. I think I'd sooner buy a mono and sho filters.....just my opinion of course.

[@CuivTheLazyGeek]

Completely understand!

[@captaindanield5827]

I ordered the 6nm version of these filters from altair. Same test report provided, same dual band pair, just slightly wider bandpass. But for less than half the price. It would be interesting to compare theses different bandpasses against each other.

[@CarlosMagnito]

Actually the best thing to recombine your OIII is to simply add G AND B together. Because your are loosing data that you've collected. CF video of Bray Falls about HOO recombination

[@CuivTheLazyGeek]

Do you mean do B+G? Should be strictly equivalent to doing 0.5B + 0.5G for instance. That HOO image was taken from quite dark locations, I feel things are a bit different from Tokyo

[@CarlosMagnito]

@@CuivTheLazyGeek The thing is he selects "Rescale Result". I don't know how much of a difference it makes but since I saw this video i'm using this technique. Maybe it's strictly equivalent with 0.5G and 0.5B. We need to do both and check !!! That's interesting But good point about light pollution. In a bortle 9 yeah... Might be different

[@AnotherAmateurAstronomer]

Interesting.

[@CuivTheLazyGeek]

Thank you!

[@grahambohl5205]

I subscribed and my astro photos are 20% better and women find me 30% better looking. I can't explain it.

[@CuivTheLazyGeek]

Oh wow, unintended side effect 😂

[@derekbaker3279]

🤔Perhaps you get better looking because they are staring at your astrophotos, not you? 😉😁😂

[@antonsinitsyn6420]

Is it better than askar?

[@CuivTheLazyGeek]

I haven't tried the Askar ones so I can't tell! I'm not sure about Hb SII as a filter though, I prefer capturing OIII twice

[@antonsinitsyn6420]

@@CuivTheLazyGeek I've never used any filters, just thinking to buy and I have only OSC camera. Askar is cheaper. Also, it have a great quality, but you'll get 6nm instead of 4nm. Anyway, please make more videos with these filters, that's awesome 🙂

“When you have personalized filter report, this isn’t going to happen “. Really? I had personalized report for IOptron CEM70. It is supposed to work better than Astrophysics. It was total sheeit. Here is another example, and you will like it. Got QHY camera; mono. NINA told, it is color. Yep, color sensor IN mono camera body. Camera came with all sort of reports. In my hands, only 1 from 4 Chinese product correspond specs. Japanese, European and US products are 100% congruence! This is reality. Example, Astrodon told “our 3nm filters will be as effective with F2.8”. It is exactly how they behave.

[@CuivTheLazyGeek]

That's comparing apples to oranges. Filters have no mechanical or electronic parts. They have band passes, those bandpasses are measured. You know exactly what you got. End of story.

[@CuivTheLazyGeek]

Also 3nm filters being as effective at f2.8 is practically impossible. Originally Astrodon as I recall tested and got decent results at F3.3. Didn't quite test at F3 but surmised it would be fine. But even at those speeds, the bandpass shift is affecting the outside of the aperture. Of course you're still getting good results, but outside of the aperture stars gathering mostly LP and degrading SNR.

[@anata5127]

@@CuivTheLazyGeek The same principal. It is just paper. There is no any evidence that it is correct. They could just write number or draw graph. By the way, they dear send you bad filters. They reputation is on the line. They already checked filters 100 times before sending you for review. Do you think I get the same quality filter? I doubt it. This is a reason you never get filters from Chroma and Astrodon. Mounts from Paramount and Astrophysics. Scopes from AP, Tak and TEC.

[@anata5127]

@@CuivTheLazyGeek I thought the same way. I had both F3.3 and 2.8 (130 and 180 Epsilon; now I have only 130). Performed equally good for both. I thought 5nm Chroma (cannot get Astrodon anymore) will be better. It dit. I returned it.
