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.
Hi, i was trying to do my first 4x4 Panel mosaic on M31, but strangely something horribe happened to one of the panel. It turned completely blue. I integrated each panel separately and then integrated the four integration together.
 When applying LNC this turend out:
hope this problem gets solved, kinda frustrating after spending so much time on this mosaic
Â
So IÂ did just found out that the blue panel was the result of having set the normalize mode to advanced.Â
But now I still wonder why you still can see the panels along the borders
@mattmoni In tab 6 you can increase MBB to 10 or even 15% to get rid of the panel transitions.
@wvreeven I did use the MBB, even up to 50% but it wont get any better
You do have some strong gradients in the panels. What I would try is to go back to the single panels and first removing gradients using the light pollution correction tool. Make the panels look as nice as possible first and then try the mosaic with LNC and MBB of about 10%.
@vincent-mod
ahh thanks for the tip, turned out perfectly now!! cheers!
Awesome!
Very nice! Awesome we could get this sorted. Have fun! 🙂
