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, i use Beta 33.
After the intergration, i load my intergrated OSC file in the lights, than go to tab 2 and scroll down to split channels to get RGB. Click on the save calibrated light and i get this error?Â
I test it in Beta 29 and there the splitting works fine, no problems.
I guess you need to fix this in Beta 33 @Mabula
Hi Stefan, @stefanastro
Thank you very much for reporting this error. I will test it myself and fix it as soon as possible. I will let you know, if I need your data to fix this.
Mabula
@mabula-admin thanks for your response.
Do you need my intergrated light frame? Or all lights with master calibration frames of my Caldwell 5 object?
Hi Stefan @stefanastro,
Thank you very much for reporting this, this is indeed a regression bug in beta33. I have already found the problem and will fix it immediately 😉 so it can be inlcuded in 2.0.0-beta34 which will be released in the coming days.
Mabula
@mabula-admin thank you. 🤗Â je bent geweldig. Your awesome
 @stefanastro 😊Â
- FIXED 2)CALIBRATE, save RGB calibrated frames with split channels
As reported here https://www.astropixelprocessor.com/community/main-forum/error-in-beta-33-when-i-want-to-split-the-channels-after-stacking/ Â , 2.0.0-beta33 has a regression bug in the calibrated frames saver when you save with the option split channels enabled. This Null Pointer Exception has been fixed and saving with split channels works again.
@mabula-admin thanks. Now I have to wait when you release beta 34. Great job
Will probably be tomorrow morning, the release of 2.0.0-beta34 😉
@mabula-admin hi, i haven't test it yet, I am so busy to collect many data now we got clear skies in the Netherlands. But I'll try to test it tomorrow with old data, I am free tomorrow 😉.
I'll let you know
