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.
The "Save Option" popup is popping up anytime APP needs to save a file after using the bulk fits header update tool once. I reset all the menus and restarted APP and the "Save Option" will pop up when making master frames. I check all the settings and can not find anything different. I like to tap Integrate and leave my computer and it is real annoying to come back and the integration is not done because of the "Save Option" window popping up. APP was not doing this before I used the bulk fits header update tool.
I also wish APP would just skip images that can not be registered and continue the integration.
Thank you,
Daniel
Hi Daniel,
Thank you very much for reporting this.
So do I understand correctly that this behaviour will occur if you first use the Batch Modify Fits tool and then perform a regular integration afterwards?

I am cleaning up my todo list and this issue was still on my list so I double checked. This issue has been fixed for a long time already I think. I can not reproduce it.
I also wish APP would just skip images that can not be registered and continue the integration.
Please know that in the new License & Settings menu, there is an option now where you can select to have APP continue on errors and not stop.
