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.
Dear Jon @jdwood,
Thank you very much, it looks like the upload completed fine 😉 I will test and solve this 😉 !

@mabula-admin I'm also using a Mac Studio and am having this issue. It's a new issue for me and I never ran into it with a PC. What I've noticed, however, is that the banding ONLY occurs when the application downscales the integration. But right now, if I have to downscale due to the application restrictions, I can't get a mosaic to integrate without these bands. They are there every time. The awesome mosaic features are primarily what I use the application for, so I'm on hold.
Hi Nicholas Morgan @nhmorgan79,
Thank you very much for sharing this. And please accept my apologies for the delay in my response.
Indeed, the down-scaling seems to cause it on mac computers which is stlll very weird.
Can you please test your data with the latest version 2.0.0-beta30, which you can download from the downloads section at the top of the page 😉 and let me know if the outcome is the same or better?
I want to test this issue also with your data. Do you know which down-scale factor is used which produces the issue?
Can you upload your data here please :
https://upload.astropixelprocessor.com/
username: uploadData
password: uploadTestData
Please make a folder here with your name and issue like: NicholasMorgan-mosaic-apple-stripes
and upload the data there and let me know once uploaded?
Thanks,
Mabula

Hi Nicholas @nhmorgan79,
I have a first indication that this issue with weird integration lines is fixed in the latest release 2.0.0-beta32.
Can you try and test with 2.0.0-beta32 and let me know if everything is okay now? You can download it form the Downloads section at the top of our website.
I am currently testing myself as well.
Thanks,
Mabula
