Old video I know, but thank YOU for this. I'm actually getting closer to where I want to be 🙏

[@mikelockwood2104]

Just purchased APP for the initial reason of separating Ha & OIII from OSC ASI 294MC Pro data. Your video hit the target and I also learned the next steps. I know this is late in the game related to the time stamp - but a well done video is reviewable for years

[@tonygarrity3673]

Great help! Was sent here by Mike Shapiro. I’m still a newbie at both narrowband and APP but this has opened up a whole new world of imaging possibilities. Thank you to both yourself and Mike Shapiro!

Big hug from Germany - now I know what to do - thx a lot! ;)

[@AstrowithEric]

Thanks glad I could help!

[@williamshaw9950]

Just great. I've been fiddling with palette re-mapping with my AA Hypercam 269c OSC and recently mastered HOO. This has taken OSC to a new level. Brilliant. And thanks to Allen Lloyd for pointing me to this great video on FB.

[@elithic]

Very nice job! Thank you for the info!

[@allenlloyd1074]

Brilliant. I didn’t know that this was possible from a one shot colour camera. Thank you so much.

[@AstrowithEric]

OSC is awesome and giving mono a good run for it's money lol. It's great for us imagers that don't always have a lot of time to work with mono.

[@codyd6163]

Awsome , Thank you for sharing some of those settings, Clear Skies

[@EODHammer]

Very cool! I'm going to try this. Thanks Eric

[@jamescahill2643]

[@alvisedorigo5650]

Super useful video Eric. I wonder why I haven't found your channel before... Subscribed! I tried several other tutorials... some of them makes APP crash (java runtime error), some other don't emphasize the green. Very well done!

[@AstrowithEric]

Thanks! I’m glad that it was useful for you. Clear Skies!

[@paulholdsworth2502]

Hi Eric hope you're well ? You asked me to let you know if this method works with a DSLR and yes it does really well. The multiply values are very different with a DSLR but after playing with the sliders a bit it works great. Thanks again Eric brilliant video

[@AstrowithEric]

Hi Paul, thanks for the update, I’m really glad the process worked well for you and on the DSLR. I was wondering how it would turn out, glad you’ve had success with it. Clear Skies!

[@ergio1]

Hi Eric, thanks for sharing. Very useful, will try with the 5 hrs data that I collected on ETA Carina... hopefully it works, I did use a Baader Neodymium (Moon & Skyglow) Filter

[@AstrowithEric]

Fingers crossed! But this is more for OSC narrowband filters.

[@GalileoUAS]

Breathtaking in all seriousness. Question though, was just with just a one shot color or did you use a triband,dual or quadband filter for this process? Ive been really interestes in this process just want to inform nyseld well before buying my first narrowband filter and I do have APP. Thank you and again you have some skills man

[@AstrowithEric]

Thanks for the kind words, this was done using the Optolong L-Enhance filter that filters all lights except in the H-Alpha, H-Beta, and Oxygen 3 wavelengths. These typese of filters were made for OSC cameras and does a fantastic job blocking out street lights and other types of light pollution and is ideal for city residents.

[@GalileoUAS]

@@AstrowithEric Sorry for the typo but you understood my question lol but thank you sir for answering my question. So I am guessing in this process you are using the h beta to play the roll as sulfur?

[@scottneith1]

This is awsome Eric. Just wondering if you can use the light polution tool after. I am unable to get a clean image after

[@MrPedalpaddle]

The video I’ve been waiting for! Many thanks for sharing this technique, and thank you for the MLK quote.

[@AstrowithEric]

You are so welcome!

[@markmoogalianprof]

Dear Eric, thank you very much for this video, it's exactly what I was looking for. Can't wait to give it a try. I just received an 'L-enhance' filter and am eager to see how it performs. I use Hyperstar and was told that for such fast systems 'L-enhance' is preferable to 'L-extreme'. Any thoughts on that? Anyway, thanks again for the video.

[@user-cz3er6rs5g]

Excellent video Eric. I’ll try this approach with some old data. It wasn’t clear to me if you had used a narrow band filter? Thanks and greetings from Austria. Regards Derek

[@dalep2842]

Hello Eric, Great tutorial and I'm planning on giving this a try with M16 image. Question, When I take my original data and run it thru the steps you recommend, getting the Ha, OIII & OIII mono frames to do the RGB combining, my Ha & OIII show in color and look the exact same. I see yours is in black and white and there is a visual difference between the two. Why is that? Now I'm a newbie to APP so maybe I have a setting wrong? but I followed your steps pretty much to the tee. Any help would be appreciated. BTW I see Mike on the Michigan Astronomy Group fairly regularly!

[@Mistr_A]

I tried the HOO but struggled with SHO thanks for this

[@AstrowithEric]

Happy to help, let me know how this worked out for you

[@whatsappvids8715]

Superb... Can do the same with DSS and Photoshop?

[@Crozb07]

Great video. It worked for me up until I tried to do light pollution reduction. I ran it on the combined image, but it completely changed the colours. It turned everything green? Do I need to run reduce light pollution on each image before combining?

[@paulwilson8367]

I see that when you do this, you check all 3 boxes on the load tab, multi-filter, and multi-session, as though we are swapping filters and going out on multiple nights. When you do this, APP shows you the red, the blue and the reddish light files when they are added. Also, doing it this way, you would have to re-load the lights etc., each time and not just push the integrate button again after selecting the next "filter". I guess you tell AP to use the flats/dark-flats/darks for "all sessions"? Or do you reload those as well? I actually tried it this way twice, and both times ended up with APP mis-matching the sizes of the stacks to each other, as though they hadn't been normalized to each other. Even though I see that APP does do the normalization tab again. Another video I watched just used the same file load for each integration and just re-selected "integrate". Do you "save" the normalized lights after each tab 5? I wasn't "saving" that tab. I can't get it to work either way. Doing it either way, my individual stacks look perfectly fine. But they will not "combine RGB".

[@ericbelanger1262]

Hello . Great tutorial. Watching you from quebec , canada ! I have a question. Im starting in astrophotography so maybe it's a dumb question . When you integrate, do you have To use your calibration frames on each integration or just one time is enough ? Thank you :)

[@AstrowithEric]

When you integrate your target, APP creates master calibration files of your darks, flats, bias (or dark flats-if using a dedicated cmos astronomy camera). If you keep your imaging train intact you can reuse the master calibration frames you created in the first integration if your exposure time is the same as the first image. If the time is longer, you’ll need to get new dark frames to match your lights and make a new master dark calibration frame. But you can use the same master flat and bias/dark flat. Key is not to break you imaging train apart if you want to keep using the same master calibration frames. The moment you break it down, you’ll need to create new flats and bias/dark flat frames to create new masters. Hope that helps answer your question.

[@montygiavelli8125]

You are very good at doing understandable videos. Is there any way to do this same video using PixInsight. thanks, Monty

[@AstrowithEric]

Hi Monty, yes I would recommend checking out Visible Dark's video. Shawn did something similar in Pixinsight using a very easy Pixel Math calculation.

[@MrPedalpaddle]

Actually, when trying to use this I found it quite confusing, mainly with the data loading process - not sure what settings to use for filters

[@carolsantulis1990]

Eric, I can't seem to find a definition of the different Composition Formulas for the RGB combine (such as Hubble 2 vs Hubble 1). Do you know if there are definitions of the formulas anywhere? Thanks.

[@lwizzit]

Did you image using a dual band filter like the OptalongL-Extreme?

[@garyrear]

Thanks Eric, I will definitely be trying out this technique. Can this be done using an Optolong L-Pro filter?

[@AstrowithEric]

I don’t think so as the L-Pro is a light pollution/luminance filter.

[@ThePixelMonsters]

Thanks for the tutorial! I think the Optolong L-enhance and the new Optolong L-extreme would be great for this?

[@paulholdsworth2502]

Hi Eric unfortunately I don't have a dedicated astro camera yet so I'm using my dslr with a optolong l enhance filter and I can get a reasonable amount of HA and Oxygen so could your brilliant technique work from a dslr RGB image ? Really good video and excellent image.....well done

[@AstrowithEric]

Thanks Paul, yes in theory this should work with any OSC or DSLR, there may be some differences for tab 0 but other than that it should all be the same, oh and you’ll use bias frames instead of dark flats. Give it a go and let me know what you think.

[@doctorschulte9751]

What exact filters are you using and on what data set? Are you able to capture all this is one? Also what telescope setup... I have the 533 on a C8 edge with hyperstar- F1.9.

[@AstrowithEric]

I'm using the ZWO 533MC Pro with the Optolong L-Enhance OSC Narrowband filter. I was using the William Optics Zenithstar 126mm f/7.7 refractor.

[@guitargod1882able]

Did you use any narrow band filters? Or was this from an RGB image?

[@AstrowithEric]

Yes this was using the Optolong L-Enhance dual narrowband filter that is designed for use with OSC cameras. This is all Ha and Oiii data.

[@noypi75]

Hi Eric. Thanks for this video. APP noob here. I think I'm missing something. I only got 2 channels/integration, Ha-OIII, Ha-OIII mono? Thanks.

[@AstrowithEric]

ORBIDA FAMILY check again there should be 4 Ha-OIII algorithms. Color, mono, extract-Ha, and extract OIII.

[@noypi75]

Astro with Eric Thanks . Great channel by the way. Subbed.

[@matthilton8959]

Did you have any filter when imaging. If so which please?

[@AstrowithEric]

Matt Hilton Yes I use the Optolong L-Enhance filter.

@@AstrowithEric oooohhhhh. I've been looking at these as I plan my move from DSLR to dedicated colour cam. I've got APP but not really found it that good ( Prob more me than the software ) I went back to DSS. So be good to learn more on APP. Great video.

What do i use as my Lum if I’m using a dual narrowband filter like the L Enhance? (Edit)

[@AstrowithEric]

The L-Pro isn't a narrowband filter, it's a light suppression and and you would use it as your luminance channel filter, the L-Extreme, L-Enhance, or STC Duo are narrowband filters

[@nebula1863]

Astro with Eric oops sorry I meant L enhance

Hey Eric, I keep getting an error message when trying to Combine RGB. It says Array Index Out Of Bounds. I’m trying this with pics shot on a dslr.

[@AstrowithEric]

HI Danno, sorry for the delayed reply. I would recommend joining the APP forum, the developer and many others might be able to help answer that question.

[@jgcheak]

Eric, I have followed the process, but when I do the RGB combine it tells me that "The images aren't compatible Please make sure the data has the same dimensions and bit depth" any ideas why I'm getting this? Thanks

[@AstrowithEric]

Are you using different cameras or scopes?

[@jgcheak]

@@AstrowithEric Same Camera, same scope.

[@CentralKyBees]

I tried this will all your settings on the Lagoon Nebula. It totally blew out the whole nebula. Just a big white ball :(

[@AstrowithEric]

The settings in the video are not perfect for all images or targets, there will be changes to the calculations. Like many things in this hobby, its trial and error. What camera and filter do you use? That can play a part in it also.

[@paulwilson8367]

I have tried this on 2 nebulas shot with L-extreme. Tried it over and over again, re-watching video. I get errors every time at the end when I tell APP to "calculate". It says: Encountered error in module: CombineThreeChannelFloatBufferWorker java.lang.ArrayIndexOut Of BoundsException 29736366. Of course, no one knows what all that gibberish means. Other than, no luck. I was confused for awhile, because your vid doesn't show the loading page. I started out thinking, since we are mimicking mult-filter/multi session, that I would check those boxes. That lead to sizing errors. Eventually left those unchecked, but still renormalized every time. Something I am leaving out or putting in that shouldn't be there. Don't know what.

[@AstrowithEric]

The L-Extreme may be a difficult filter to use with this, perhaps due to the tighter bandpass. What’s your scope and camera?
