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.
So, I had been using 1.075 on trial and decided to purchase a renter's license. In the process, I upgraded to 1.077. Now it is crashing.
Unfortunately, I've no idea how to provide debugging information. All I can say is I was trying to stack data from my D5100 and D5300 like I'd done in 1.075, so I know it should work.
I got down to stacking only 10 lights, no darks/bias/flats - it stacked those. When I added bias and flats, it crashed.
System is Windows 7, 16GB, gobs of SSD. 1.075 was configured to use 8GB. I thought why not go for 12GB for 1.077, but it crashed. Reconfigured for only 8GB now.
Recommendations?
Reporting another type of crash (1.077 on OSX) when loading CR2 files (Canon 5D3): software crashes just as soon as you hit Open on the open file dialog.
HOWEVER: this seems fixed (with the exact same files) in 1.077.3

Okay, found how to revert to 1.075, reran a simple stack and it worked fine. Going to go with something more adventurous that previously worked in 1.075.
Thanks for reporting these issues. If you would be able to, could you upload your data to our server? Login with username and password: appuser
Make a directory in it with your name on it + "1.077-crash" and upload in there. Thanks a lot!
This will make it possible to have a good look at to what is happening and solve the bug as fast as possible.
