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.
I am trying to edit one APP processed fits file. The error says no space left on drive. However, that is not true. System Information shows 1.02 TB available of 2.12 TB. I have rebooted the machine several times but APP is stuck on this error.Â
 Thanks for any advice.

Mm, does it work when you move the data to, for instance, your documents or pictures folder? It may have something to do with how the OS is reporting this to APP. And maybe check if APP has permission to that location as well in the Mac OS settings, might be that it's blocking APP.
@vincent-mod and me have been discussing this offline. Apart from moving the data out of the Desktop directory, could you please try to reduce the length of the names of the directories and remove the spaces from them? Perhaps a path as simple as
/Users/andynowlen/NGC7822
could be a solution. If this works then this gives us a direction for trying to reproduce the error so Mabula can implement a fix. Thanks a lot in advance for trying this!
