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 am using Darks, FLat, Bias.

Failed on all 33 frames.
I know the light subs are good. Shot with ASI294MC Pro Cooled to -10.
I can run everything through Nebulosity and the image comes out great.
I have run other images through APP with no problem, this just started 2 nights ago.  Tonight with all new subs it again failed.
I have set the (Kapa) down to 1.5 after reading some other post on the subject, but it did not help.
Can you show me one of these failed lights? Just upload a stretch here. Thanks.
Thank you! So the first thing I see is that it's not in focus, so maybe APP disregards many. Could you try to set the pattern recognition from quadrilaterals to triangles (Tab 4) and see of that works?
Ok will give that a try
Set tab 4 to triangles. still getting the error.

I know the focus may be a tad off but I would think not that bad.
APP ran some subs the other day that were kind of terrible.

Well, sorry to say but the focus is pretty off. The FWHM is about 17, while normally you should be around 2-3 most of the time. Could you upload a second of the frames that failed? I can then see if I do get them registered as the one above, APP did find enough stars to do that.
Also, did you change any other settings or are these all at the default?
All other settings at default.
I used the focus assist in the ASIAIR.  I have a focus mask on the way. Hope it gets here before my trial runs out.
Thanks you for the speedy replies and help.
You can ask for an extension to your trial if you want, if you need that bit of extra time to test it that's fine.
I will do that. I think my trial ends in just a few days, will be after the 15th before I can purchase it.
From what I have seen, I like it.
