2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
hi,
I have a set of 40mm DSLR data which seems more difficult. APP does not allow me to search the comet. I see the first screen shortly, than APP tries to find Neowise by itself for all frames. Maybe a "force manually finding the comet" would be good. I attach one of the errors encountered processing the data and a single frame.

Ok, so the actual error is that it skips the manual selection? Didn’t see it do that yet (at this point it actually is a requirement), are you sure you didn’t click in a wrong place (just to be sure)?

repeated this several times, first thought so, too. but no, did not click every time I am quite sure
Interesting, would be great if you can share this data with us to check.
Go to https://upload.astropixelprocessor.com and use upload1 (or upload2 till 5) as username and password will then be the same as the username.
Create a directory named “elgol-COMETselectionissue” and upload in there. Thank you!

hi vincent,
the login does not work after 3 attempts. maybe try this here:

Oh that is weird, you did use upload1 as username and upload1 as password?
I’ll give your link a go this afternoon, thanks.
@vincent-mod
so, I guess the comet algorythm has problems with the foreground. I cropped it and everything worked fine. Maybe insert something that stops this irritation.
this is done with the data in 3 different stacks: forground, stars and comet merged in photoshop
stefan
Thanks for sharing that, I'm starting to work on it today, have a bit of a data backlog. 😉
Ok had a look at the data, loaded everything in, went to the register tab and selected "comet" registration and it did ask me to point to the comet. Worked fine with the foreground. So unfortunately I can't reproduced your issue at the moment.
I can get a bit of that blue tail out of it, nice. But your combination above makes it much better even. 🙂
