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.
Dear all. In the 2.0.0-Beta6 (Windows) release, in the "separate windows" view, top left pane, there is at the bottom a box called "right button".
It doesn't do anything, but it increases in size onze you enlarge the window, eating up valuable screen real estate.
It's the minutest of RfC's, I know, but therefore probably also one of the easier ones to fix?
Mm, I've seen that one pop up before indeed. Going to investigate further, thanks for the heads-up.
Hi Petra @petelaa,
Thank you very much for your feedback 😊 !
I am glad this old issue is gone now! Sorry for not notifying you earlier about this fix, I think it was fixed various versions earlier...

Hi Mabula,
Unfortunately, I was premature in my happiness. The issue is gone when using my second screen, but still there on my laptop. When I get home I’ll try to (not forget to) post a screenshot.

Hi Petra @petelaa,
Can you try the following for me on your laptop? Please reset all setting to it's default using the button in the new License & Settings menu. Is the issue still there then after the reset? If so, what window configuration are you using? Do you have the frame list panel in it's own window? Image viewer as well? Or is everything in the main application window?
Thanks for reporting this. I have never encountered the issue myself, so please share as much as you can so I can hopefully duplicate the issue and finally solve it 😊
Mabula
Nope 🙁
- still there after reset
- both in the default config (although smaller) and in my preferred config
- see screenshot: image viewer as a separate window, frame list separately as well.
- "right button" only appears on the bottom of the main window.
strangely it was gone after I first downloaded beta33, but as soon as I switched from a two-monitor setup (my home office) to a one-monitor setup (my couch) it returned, and hasn't left since.
Hi Petra @petelaa,
Thank you very much for the details. I have made a new issue on my list to address this as soon as possible. Does the "Right button" still appear after a new reset in APP and then again detaching the frame list? Or does it only occur when switching from two to one monitor?
Sorry for more questions from my side, I think I that I do have enough information now to get this fixed finally 😉 I will report back later when I think that I have fixed it.
Mabula
Hi Petra @petelaa,
Good news, I can duplicate the issue now with your detailed description. Now we go and solve it 😉
Mabula
Hi Petra @petelaa,
Thank you very much for reporting this issue again and for submitting all those details so I could duplicate it.
I have found the issue now and have properly fixed it. I also saw that the weird Right Button could pop-up when working in tools like the Remove Light Pollution Tool when the frame list panel was in it's own window. Any change in the window size of the main application window would show that weird button... No longer in 2.0.0-beta35 😊 I aim to release it before March 15.
- FIXED "RIGHT BUTTON" at bottom of main window with frame list in separate window
As reported here: https://www.astropixelprocessor.com/community/rfcs-request-for-changes/beta-2-0-0-beta6-qol-rfc-right-button-box/ , if you have the frame list panel in a separate window (You can set that in License & Settings) then in some cases a weird and big "RIGHT BUTTON" can be shown at the bottom of the main window. This has been fixed. The issue could also be created when you are in tool like the Remove Light Pollution tool where the frame list is automatically hidden. This has also been fixed.
@mabula-admin thanks Mabula!
Even though the issue itself was very manageable, and just intriguing, I’m glad it got resolved anyway.
Thanks for all the good work, this is a great piece of software!

Hi Petra @petelaa,
Thanks 😉 ! and you are most welcome ! I am also glad that this one is definitely gone from our issue list now...
Can confirm, it's working as expected on all monitor setups I use. Thanks again!
Awesome Petra @petelaa, thank you very much for your feedback, persistence and patience as well !
