This is HUGE. Just got the 2600MM camera for Deep Sky and needed to figure out how to do this, as I am only used to using the 2600MC version. Clear, concise and not a lot of fluff! Thanks!

Excellent, direct and clear, thanks for teaching of this, which I was wondering since soon I shall be processing H-S-O, cheers and CS!

Yes! This video is the best! Should be in everyone's playlist.

Great info! I knew about the reference frame already but hadn’t considered being able to use it across multiple separate colours. So, the learning curve steepens yet again.

If there is one thing I have learnt, it's that the learning curve never ends, and seems to be constantly getting steeper! Clear skies to you.

Great info Matt! Thank you!

Thanks, Caleb!

Thank you so much for this material. It was a pain to arrange the photos so that they coincide. You helped me so much :) Regards 💪

Thanks!!!

Photoshop can also do this sort of stack via Photomerge, btw.. but yes, I use DSS for this sort of thing

Because you already have your offset frames in DSS, you don't have to import the master files. Just select your S2 and the offset files and stack them. Then O3 and offset files, finally Ha and offset files.

Thanks, Wilco - thought that was the case, but it takes too long to check that manually! At least going forward I can save those few seconds - appreciate you taking the time to comment! Clear skies to you.

at minute 8 of the video, how can i align the rgb levels in PS ? The automatic alignment doesn't work anymore. For the rest very good job! Thank you

Interesting, but APP is THE stacking program of thr art. So don´t wonder if you´ll have not that many klicks..

Aah, the classic battle of the softwares! APP is good - it just never produces images as well as DSS for me - though that is probably a user issue! APP defo has more functionality, but it's also not free. Still a lot of people out there committed to free software, DSS included - especially those just starting out in the hobby! Clear skies to you, my friend! :)

APP does a lot of things but the price is pretty high. DSS does what it’s expected to and does it simply. There’s a whole lot of folks out here using DSS who would find this interesting and useful.

@@EverydayAstro All right! Thank you

Never having used DSS, never having used a monochrome camera and you, apparently, not having shot and grouped all the frames one would normally shoot, I found the explanation somewhat confusing. It would be useful to know by type exactly what frames would be shot in the normal course and what in what group each type of frame should be included. My best guess is that for each of Ha, OIII and SII you shoot a complete set of lights and flats and then group them by filter. So, then assuming 50 lights and 100 flats and 100 dark flats, there would be three groups each containing 200 plus, for each group a complete set of "master frames", whatever that might be. Please explain this without assuming prior knowledge of DSS and monochrome shooting.

Hey man - sorry, this was more about what to do once you had the photos to make sure they all aligned properly. When collecting the photos you need one set of Darks (filter is irrelevant as it's dark!) one set of Bias/Offset (again, they are taken in the dark so filter is irrelevant). You will need a set of lights for each filter (LRGB or SHO) and a set of flats for each filter. Because the focus point for each filter is different, and the dust pattern on each filter will be unique, the flats should be done for each filter separately. The focus point part is a little less critical in my view (dependent on your filters) as there isn't usually much difference in focus position. I personally write down the position number of the ZWO focuser for each filter, then when I do the flats, I can just tell it to go back to that position and I know it will be pretty accurate. The dust pattern part is critical though - so make sure you do flats for each filter. So lets assume you have an SHO image. You should have X number of lights for each S, H and O filter. You should have X number of Flats for each S, H and O filter - then one set of Darks and one set of Bias that can be used for all of the filters. Does that make sense?
