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.
Getting this error in Normalize that essentially halts process with multiple error windows saying that same thing. Never seen this before but it has happened last few workflows. Nothing else has changed in terms of camera or image acquisition (FITS via SharpCap). It is a non-recoverable error. Help!

I have also encountered this srror... any ideas?

I posted the error in this forum and in a Face Book group. Got no help. I did the following to address the issue:
- Noticed on my Windows 11 laptop that Java was not installed so went ahead and did that (I suspect a Java error is involved). This helped on one processing run and not the other where more frames involved.
- Installed APP on a MAC desktop unit (you can do multiple installs). I bring all the image files over on a Samsung portable drive and APP so far has run perfectly on the MAC. Not the most convenient solution but it works.
I suppose we could also go back to a much earlier version but then lose any "improvements" in version 2. Too bad the author did not reply to help - we cannot be alone with this bug.
This error continues to plague my processing.. I can go weeks and everything is ok and then it strikes again.. After many years of using APP and the lack of response it is about time I made the move to stacking in Pixinsight..Â
I am having the same ongoing experience. Often a restart and rerunning of APP works ok. I still think it's an external Java issue as that module has to be ended in Task Manager to clear the errors. Frustrating......
I usually process in Pixinsight and have decided to bite the bullet and learn WBPP for stacking and this has solved my problems. As I shoot Hyperstar the number of subs often exceed 200 by 50mb and neither APP or PI can do this quickly and my stacking runs are usually batched overnight. A failure in a big overnight run becomes a real set back.
