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.
During Integrate process it stops with this error message that I dont understand.
An solution?

Hi @ziofrancotto,
Thank you very much for reporting this issue and welcome to the APP forum.
Did you try this with the latest APP version 2.0.0-beta32? If not, can you download the latest release from the Downloads section at the top of the website and let me know if the error still occurs or not?
The error seems to indicat a problem with either normalization or registration of 1 or more of the images. Can you try the following for me.
Load the images and your calibration frames if any and process up and until 5)Normalize. Then before integration starts, what is reported in the bottom frame list for registration and noise values? Are all frames processed normally until that point or do you see problems with some of the frames?
We have 1 other report of this issue, so we need to know what is happening here and solve it as soon as possible.
It will be most helpfull if you can also upload the dataset on which this is happening so I can explain the problem and solve it as well for the next release.
Can you upload the data here:
https://upload.astropixelprocessor.com/
username: uploadData
password: uploadTestData
Please make a folder with your name and issue, like: Francesco-ImageNormalizer-bug
And please upload your data into that folder and then let me know, so I can take a look as soon as possible.
Thanks!
Mabula
