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.
I'm trying out APP. Calibrated my frames. Hit <analyse stars> and the program gets part way through my stack of calibrated frames then the Console goes black and APP just hangs and stops activity. Has happened 4 times now. I tried upping the memory to 8gb and it got to 37 of 38 frames then hung again. Any idea what's going on?

Increasing the memory seemed to help. Didn't realize you have to restart to update memory setting. Have gotten through to integration now without problems.
I have a problem when i load ha, oiii, sii data and i get to analyse stars it always reports oiii as failed but processes ha, and sii without any problems at all. Running a mac pro with 64 g of memory, if i run the stack thru pixinsight and then put the single image with the group it is the only way to continue. Any help
Thank you very much for reporting your issue. I just finished extensive work on a greatly improved Star Analysis module for the next release APP 1.076.
BIG IMPROVEMENT, STAR ANALYSIS, extensive work has been done on improving star detection and analysis, due to some users reporting issues with Star Analysis in APP 1,075 ( https://www.astropixelprocessor.com/community/rfcs-request-for-changes/problem-with-star-analysis-1-075/ ). I am happy to announce that all reported data that gave issues, now works flawlessly. The Star Analysis module is also twice as fast now while becoming much more robust and memory consumption is kept very low as well. Users will notice that APP will detect more stars on more datasets as well. Here are some performance graphs that show Star Analysis of 100 H-alpha frames of 5 different optical setups, for 4 CPU threads, 8 CPU threads and 16 CPU threads, APP 1.075 versus APP 1.076:
If you want, I will test your data as well to make sure this works propery on your data as well. If so, can you upload it here:
