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.
This is likely an uncommon use case, but I'm posting it here in case the fix is relatively easy.
Some of us stack our data on powerful machines, then post-process the stacked result on laptops that we can use from a variety of convenient locations. Â Sometimes this is just a convenience, but sometimes it's by necessity -- such as when all your raw data is at an observatory without a fast internet connection. Â In my case I stack on a powerful machine at the observatory and then transfer the integrated result to my laptop instead of transferring 60 GB of raw subs.
Using Mac OS Sonoma 14.0 screen sharing, I have encountered a usability issue when connecting to my Mac OS Sonoma stacking machine running APP: Â The mouse pointer blinks, and sometimes disappears when I stop moving. This makes navigating the APP UI difficult when connecting remotely.
If I switch to another program on the remote Mac, the pointer works fine. Â This seems specific to APP.
If this is not common enough to be fixed, or is outside your control, I understand. Â Just pointing it out.
Hi @mountainair,
That sounds very weird, the mouse pointer is not manipulated in any way by APP code but must be drawing mechanisms of either:
- the operating system
- or our development platform
Maybe there is a bug there somewhere. For now, can you describe how this works on macOS? I have never used screen sharing with mac computers, but I should be able to test this between the different macs that I have. Where can I enable this screen sharing that you do? Do you know of other ways to share your screen?
