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 running into a problem with some of my ASI1600MC images where, after analyzing the stars APP gives the error: "APP can't find any suitable frame to be used as a reference frame" when I try to Register the frames. I cannot manually select a reference frame because APP reports that any frame I choose is not suitable because it must be star analysed first even though they have already be analyzed.Â

Hi JandaC,
Thank you for reporting this problem.
This is problem that occurs if the amount of stars that is analyses is too low. This can happen in version 1.055 due to the default value of: detect above noise level kappa value. This problem will be fixed though in in the upcoming version 1.056.
For now, you will need to lower the kappa value in 3)Analyse Stars. Lower it to such a level that you detect at least 100 stars in each frame, (a little bit more, like 500-1000 is nice if the data contains that many stars).
The amount of stars that are detected and analysed are reported in the bottom frame list panel, so you can verify that before starting registration.
In the upcoming release 1.056, this kappa value will be automated, so that will be much easier 😉 and I have fixed several issues and bugs that could pop-up if the analysed star count was too low.
Let me know if this helps 😉
Mabula
Yes. That fixed it!
I've got a trial license which I will definitely be upgrading. I don't see any way to do that.
You might want to consider an "Upgrade Now" option in My Account.

Hi Jeff,
Excellent 😉 and thank you for your feedback!
The upgrade option is to order either a Renter or an Owner license. If you order one, you will automatically get a new license code to upgrade the license in APP.Â
Kind regards,
Mabula
