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.
after installing APP 2.0.0-beta39Â i cant find "Ha-OIII extract Ha" or OIII... i tried it under extract H-alpha and my stacked image is in color!!!
what's going on. it worked great on the older version using duo band filter but now.
Dear @rcfmitch,
2.0.0-beta39 has not been released yet... the version on the downloads page is a major beta test version which should not be used really. I will remove those. Beta39 once released will have better duo-band options, so the beta39 that you used was work in progress on that. The test version was uploaded for several users to test new mosaic algorithms.
Sorry for the confusion, once beta39 is actually out, it will be notified everywhere.
Edit by Mabula: I have removed beta39test1, beta39test2, beta39test3 now from the downloads page.
Mabula
my fault, here is my version:Â 2.0.0 beta 39test 02.
can you recommend the best duo band APP version.? please.
Hi @rcfmitch,
Best to use the latest official release 2.0.0-beta38 😉Â
Beta39 will have new options for dual-band processing and I was already working on that, paused it to resume work on the new registration engine which is now nearly ready 😉 so I can finish the work now as well on dual-band processing. Once ready, beta39 will be released !
Mabula
Hi @rcfmitch,
A separate noise reduction tool is planned to be implemented after the 2.0.0 stable release. Beta39 is soon there with the new registration engine and Dual-Band options. Then final work is done for 2.0.0 stable and a full manual will be released as well.
Mabula
@mabula-admin That will be a huge game changer( Noise Reduction) for us that depend on APP , as the Primary Processor.
BTW , the older version that you suggested worked out great for extracting Ha/OIII .
TY. Mitch
Please put me in the Beta testing stages . if there is such a thing. 🙂 😊Â
I have 8 years experience with Pix....just a thought.
Hi @rcfmitch,
Great and yes I understand that 😉Â
Okay, if we need beta testers for something, we will think of you.
