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.
Hey!
I'm after updating from 1.075 to 1.078 I'm getting the following error when I try to combine two integration results.
Steps to reproduce:
- Load several integration results as "lights"
- Go through calibrate (nothing to calibrate), analyse stars, register (all works fine)
- Press "normalise" after a few seconds the error message shows up as on the screenshot above.
My setup:
- APP 1.078
- macOS Catalina
- Sorting set to "quality"
Best regards,
Anton
Thanks for showing the steps! We will try to reproduce them.
Hi Anton @tonyveo,
You are trying to directly process monochrome and RGB data, this was not possible in older versions and is not possible yet in 1.078.
But... I do plan to make this possible in 1.079 😉
So you need to split your RGB first in separate channels which you can do in 2) Calibrate, split channels and then save calibrated frames. You will get 3 monochrome R,G,B channels which you then can combine with the H-alpha data.

I didn't even notice that. 🙂 Ok, that explains it.
Thanks a lot! Thank worked 🙂

Hello @mabula-admin
As far as I can understand this is still not developed ? Cause I had the same issue and finally worked after splitting my RGB image.
Thanks!
It was indeed his intention to get that workflow improved, but other priorities took over. It will come though, he has a shortlist of features on which this is one of the things he want to get implemented rather soon.
