Altair 6nm Dual Band Filter Review: A Light Pollution Killer

[@Mark_Wierda]

5:27 Is that Grolsch beer on your right? Greetings from the Netherlands. Great review of the filter 😁

[@Wheeljack678]

A cooled, dedicated astronomy camera is such a gamechanger it is hard to describe. I used a modified T5i too for about two years and I was really happy with the results it produced. I bought a Player One Poseidon C-Pro a few months back and the difference in quality just can't be compared.

[@IrfanBayuaji]

What makes it more crazy is the non-existed bloated stars and the texture of the nebulae it can come out with. Great recommendation, Walt!! 🤩🤩

[@petooskey]

These kinds of filters are a game changer. I just got my first actual rig with an ASI294MC and a Svbony dual band filter and it blows me away with how much it brings out all that hydrogen

[@johngiromini5745]

That picture of Thor's Helmet, NGC 2359, (14:12) is absolutely amazing! Very nicely done.

[@deltaastrophotography]

Thank you! I was pretty shocked at how well it turned out after only 3 hours! I'm going to try to get at least three more on it.

[@Erniej270]

Great video and images! Welcome to the world of cooled dedicated Astro cams and dual narrowband filters. Increases the fun factor!

[@jillratanapan2606]

Your reaction-PRICELESS!! Thank you soooo much for this video. As always, YOU ROCK!!

[@davidpippin3460]

Love the Clarksdale shirt! Reminds me of the old Greenville slogan we made fun of 'Greenville-Catch the Spirit!" Really enjoyed your excitement with the cooled camera!

[@deltaastrophotography]

Speaking of the shirt, it was funny to see the footage I shot when I first got the filter compared to just this past week. I was able to wear a t-shirt at night and by the end of the video I'm wearing a coat in my house.

[@Saints2009Champs]

@@deltaastrophotography MS weather for ya.

[@Alan-vk6bk]

I love your off the wall style of videos. Really appeals to my wacky sense of humour. Keep up the good work 😂😎👍

[@deltaastrophotography]

Thanks! I'm glad I get to just be myself and people appreciate it.

[@Thephysiquemechanic]

Wow those pictures really blew my mind at the end, that filter is something else! Also is that a real-to-reel in the background towards the end?

[@davidstillman9434]

Hey Walt! Wow great site. Nice to meet you at the Wharf last night (I was the guy at the bar)

[@deltaastrophotography]

Great to meet you guys! I hope you enjoyed that eclipse as much as we did!

[@d.fresh.750]

Some really awesome shots at the end...and nice video! I have the SVBONY SV220 like a lot of people commenting, but I've only used it once. I got a nice HOO California Nebula out of it though!

[@keithhanssen7413]

Outstanding! I like your style, mister.

[@seventhsun1]

Wow, great pictures Walt! well done

[@andesastro]

Great review! Ive seen a couple of peeps sayin these filters help even in very dark skies, i would agree to some extent as they will also block reflection bits and faint dust and IFN! Dont be scared to go for more minutes exposure in the city, although that band seems very odd, maybe sensor related? Check it out with your new 294mc pro. You should get a filter wheel and an S2 O3 filter now to create SHO palette and help us with the workflow. Thanks Walt! PS: what was the last targets name? Very cool one.

[@deltaastrophotography]

That dark band has always been a problem with my Canon camera when shooting in light polluted areas. I wish I knew what causes it. The last shot was the Tadpole Nebula!

[@KevinRudd-w8s]

Good review Walt. I live in the UK and it is the VAT which runs at 20% that makes everything expensive. I use a lot of Altair Astro products, I have in fact just bought one of their 115mm f7 refractors though I think this is the same scope as the one sold in the US under the Astro Tech brand. Their high end filters look really good but are also very expensive. I use their 6nm narrow band filters and are very happy with them.

[@deltaastrophotography]

I'm definitely happy with their filters. I would love to try their cameras at some point. I don't want to be an all ZWO guy.

[@golfbiker100]

Hugs, great video, so right, sometimes you’ve just got to look at what you’ve shot, that thrill is what it’s about

[@DrJ_MKE]

Great video Walt ! Very informative. I shoot from a Bortle 8 zone with a full spectrum DSLR viewing through a 70mm doublet refractor on a SWSA GTi mount. My question for you is: can I use this filter with no guiding and shorter exposures ? I typically expose for

[@bobcarn]

Besides picking up some good information (I'm very much an amateur) here, I got a real kick out of seeing all of your Grolsch bottles. LOL! That's my go-to beer and I wind up keeping the bottles for all kinds of things.

[@deltaastrophotography]

Man we can't get Grolsch here. On the rare occasion I come across it when I'm traveling I have to buy as much as I can and save all the bottles!

[@jesuschrist2284]

I just thought id let you know you've taught me to hate clouds and light pollution. Ty ;)

[@allenbaylus3378]

what would be (in your opinion) the best solution for shooting Galaxy in Bortle 4-5 regions. I noticed how dark the sky looked at night a year ago when I put a L-Extreme in my light train. It was amazing. Glad to see that they have a HA-OIII and SII-OIII combo available.

[@deltaastrophotography]

I just got the Skytech LPro Max. It's been doing really well with galaxies. Even better than my Optolong L-Pro which was also really good.

[@mikehardy8247]

This review and Cuiv's made me do it! Askar Sii-Oiii, with SV220 combo, brings out amazing detail in my bortle 9. Many filter choices.

[@mikehardy8247]

The IDAS GNB FILTER, is supposed to do galaxies justice. Watch Cuiv's and Lukimatica' contrasting reviews

[@mikehardy8247]

The Idas GNB is supposed to work well. See Cuiv's, and Lukimatica contrasting reviews. It might be what I'll get. I use a simple UV/IR now.

[@stuartpinkney2340]

Thank you for doing this video. Seriously it’s so helpful and informative. I’ve got a quad band from these guys and that’s very good but this looks like a game changer.

[@mikemoran5439]

Very nice. I think you sold me on this... FATALITY!

[@NeilArthurs]

Absolutely wonderful results!!

[@ujjwaldatta6713]

Hi Walt!! Happy New Year. Great video as usual. Quick question. I have a Canon drop-in filter adapter. Does this 6nm filter for Ha and O3 from Altair fit in that or I need a special filter adapter? Other than Altair, does any other company make the Ha-O3 Bandpass filters that can use with the Canon’s drop in filter adapter? Thanks.

[@hangerbird]

I have the RedCat 51... Do you know if this filter would work with the Starizona RedCat DSLR Filter Slider Adapter Kit so that I could use this filter?

[@UNLKYHNTR]

Crazy stuff. Absolutely outstanding!

[@Jay2161]

"I gotta stare at this for a little while" ONE MONTH LATER 🤣

[@deltaastrophotography]

I mean... Sometimes you just have to take a break and really take in what you just photographed! 😂

[@LearningAstrophotography-jj9en]

Great video and thank you for the info on the filter.

[@dw.in.michigan]

Those were awesome images!

[@EvenTheDogAgrees]

"I gotta stare at this for a while", followed by a title card "One month later". OK, I know who I'll never challenge to a staring contest...

[@mikehardy8247]

Even at this price, filters are costly. Seems every month a new one is reviewed. I'm in bortle 8-9, so no doubt this would benefit me. Im using the optolong L-enhance now. Comments about the SV220 peaked my interest. Its $130 right now. But the Altair has documentation. Is the bandpass acuracy of the SV220 as good (repeatable) with all pieces?

[@davidletz9123]

Great images, Walt. Do you use a filter drawer on your "optical train?" Also, did you polar align without the filter?

[@deltaastrophotography]

I don't have a filter drawer yet. I just screw it into the flattener of my telescopes. And I do polar align with it. Works just fine with five to ten second exposures.

[@rizen3467]

Great video! I'll put this on my (long) gear purchase list 😂😂

[@Teqzyy2Sober]

Could i attach this to a camera and use a lens with the camera?

[@DarkTrapStudio]

Where do you posts/sell your photos ?

[@AstroDanno]

You should try setting up in downtown Memphis next! 😂

[@deltaastrophotography]

I once went to a rooftop party downtown. That would be a fun place to setup!

[@bokvaj]

antlia alp-t is 250 usd + tax, 5nm and is for me working really great. But yes, you dont get the measurements.... ;)

[@mikemoran5439]

FIGHT!

[@DarkTrapStudio]

WOW !

[@ScottDavies]

Really fun and great video ❤

[@varadinagypal]

Actually, I know of at least one company that did it, but let us not advertise them, as I quite like Altair Astro -- let's advertise Altair Astro :D.

[@deltaastrophotography]

Yes let's!

[@JemCruz]

Walt, mate what are you eating?! You need to add veggies too!

[@deltaastrophotography]

Ok I'll take a cactus 😂

[@DLMVegas]

Why do all these astro filter companies cater just to Canon users is what I'd like to know.

[@deltaastrophotography]

I don't know. I feel bad for people with these really nice Sony and Fujifilm cameras.

[@michaeldesignbig2538]

i see terrible halos with this filter

[@jesuschrist2284]

Stop down experiment maybe?

[@nikaxstrophotography]

I love your video style Great review. Just a note I use an optolong L-Ultimate at 3nm and have no issue plate solving or polar aligning or autofocusing with my scopes and asiair. Just increase the exposure by a few seconds

[@deltaastrophotography]

A friend of mine has that filter. He had trouble at first but started increasing his exposures as well. For me that filter would probably be overkill. You saw how I can get five minute subs with no filter and have zero light pollution problems. I should have said something in the video about increasing exposure time with these filters. Thanks for bringing it up! Cheers!

[@nikaxstrophotography]

@@deltaastrophotography I'm in Bortle 6 skies and these filters are a must with narrowband targets.
