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 have been using APP for 3 years and I am dismayed by the lack of some basic functions that are still missing. I thought in 2018 that those would come quickly as APP was young back then and it would evolve. To my regrets, we are still waiting for those to happen in 2021.
THREE of them are basic software-expected-features in 2021:
1- an UNDO/REDO button;Â to bring you back in an instant to a previous version of an image while editing,
2- a SAVE USER PRESET when stretching images.  It is impossible right now to save settings that works well on my images after an editing session. This is true for stretching less than 10%. Â
3- A "save session" capabilities.
This one is a bit more complicated to implement:
4- There is no preview available before making a change on the entire image which often take time.
I will strongly consider Pixinsight when my year subscription will end.
Â
Best Regards
Hi Stephan,
Yes, some of these are missing and we know it's something quite a few would love to see. I can say that Mabula is changing the way he releases software a bit going forward. There will be more incremental updates again and he has prioritized the saving of settings now. In the past he said 1.085 would have that and he now has made that a priority for 1.084. 1.083 is also around the corner now.
