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 there,
I just upgraded to the latest 1.080 version, but after stacking i got an error and i can't find my sulphur stack in the list.
It has been written in the working directory, so no real problem.
But i proceeded to try and use lpc on my h-alpha and Oiii images, but after every save, i get this error:
Encountered error in module:
ConstructFrameDetailsListWorker
Error message:
java.lang.NullPointerException
Cause:
null
mT.a(Unknown Source)
mT.compare(Unknown Source)
java.util.TimSort.countRunAndMakeAscending(TimSort.java:360)
java.util.TimSort.sort(TimSort.java:234)
Anyway, just thought i'd let you know.
Thanks for reporting! This shouldn’t happen indeed and seems to be specific to your case. Is the location where you’re saving data somehow write protected or in an unusual place?
@vincent-mod
Files were saved ok.
After I restarted APP everything works fine again, but I had a very big project open. multiple nights, different callibration frames for different nights.
So I didn't really want to restart it.
Still, I wanted to report it, just in case.
Mmm interesting. Thanks for that, we will keep an eye out on this, if it happens again, please report again and we will have to treat it as a bug. 🙂
