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.
Hello All,
I am a new user still in my trial. I apologize if this is not the correct forum to post this question. So far I am really impressed with the stacking ability of APP as opposed to Siril and PI. There is one concern I had an I am not sure if there is a workaround or option to prevent this message. I am using a SeeStar S50 so I have 1000's of 10 second subs. When I load all my lights and start the integration process I often have some level of failure in the Star Analysis and Registration section. I get the attached pop-up and the process will just stop until I click integrate again, confirm the name of the file again, and then it will move to Register. If anything happens during Register I have to repeat the process a second time. Is there anyway to disable this pop-up and have APP just process everything from start to finish without having restart the process multiple times. I want to be able to start a complicated stack or mosaic that may take hours and let it work overnight, if necessary, without reconfirming everything multiple times. I have tried adjusting the options in the CFG menu but so far nothing prevents the pop-up. Thanks!

You can uncheck calibration warnings in calibration tab but that's all I'm aware of.
I think at step 3 you can de-select all the files that have warnings - try sorting by clicking on the titles at the top of the file list - very useful.
Thanks for the suggestion, I did try uncheck that box but it did not make a difference. The integration I tested was 629 subs for M16. 2 subs failed at Star Analysis and 627 were integrated. I even tried to lower the total number of subs to integrate to 600 to see if it would bypass the rejected subs but it still had me click the integrate button again to move to the Register phase.
