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 tried to do a short integration on Comet C2023E Atlas, only 5x each of LRGB at 60 seconds each, and it hit 74% on integration, then stayed there for over 12 hours in a completely unresponsive state. I finally used task manager to kill it this morning. I had 97 gb free space on the C drive which I was using for everything, a 400gb Intel 750 nvme drive. I have plenty of RAM at 128gb and an 18 core/36 threat Xeon in this computer with an AMD 6900xt video card so it shouldn't be resources. Here is a screenshot of it:
Hi @imnewhere,
Thank you for sharing this.
This is a bit weird and very likely not specific to beta20, because nothing changed in the integration module in beta20 when compared to beta19. The process states it is at 74% but the process console shows it is just loading the first image, that is not correct. I think the process console is not showing the last lines is it?
At 74% the integration process should actually be integrating the last pixels before closing. Did you check the output in the general console? Did this problem occur more often or just once? If just once, it is likely caused by your Operating System or other software claiming/blocking the harddisk probably.
So my suspicion would be that it is probably be caused by a block in IO for APP (read/write in the storage device/harddisk) I would think. Like your operating system or security software blocking APP somehow.
