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.
Hello, I was pretty happy to see that APP uses dynamics RAM, but I have a question, is it possible to increase or decrease RAM that APP used?
Thanks a lot.
@alexlee24 That version allocates all but 2 or 4 Gb of the system memory and only uses of that what it needs. This cannot be lowered. Since APP only uses what it needs, and this usually is much less than the available memory, the performance of the rest of the system shouldn't be affected.
Why would you want to be able to configure this yourself?
@wvreeven I have 32Gb RAM(Kingston 2666 8gb*4), and show APP can maximum use 28Gb of 32Gb, but some time APP or Windows10(resolution) will crash when start processing, I'm not sure is RAM problem or what, but it nearly uses full of 28Gb(become red) before my PC has a problem.
The solution for me and now is to do nothing and just waiting APP to finish his job. 🤣Â
Thanks.
@alexlee24 When APP is using the allocated 28 Gb of memory, what are you processing? Are you perhaps trying to create a big mosaic or processing a LOT of data?
@wvreeven Yes, about a total of 7000s files with 3-degree LNC and 20% MBB.
@alexlee24 Do you really need the LNC? It is very resource intensive and in most cases not necessary at all.Â
If you do need it, consider splitting up the data set into smaller batches of, say, 1000 files or even less. Once done with all batches, you can load the individual integration results (one per batch) as light (don't load any calibration data) and integrate those together into a final result.Â
@wvreeven Ok, I will try. Big thanks! 😀Â
