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'm sorry, I must have a different version. Once I clicked cancel, I cannot find a way to resume the process. I had clicked "integrate" and quickly realized I want to make a minor change. So I hit cancel. It will not let me resume. Do I really need to start all over again????
It has happened to me several times, I cant locate when or why it freezes. Sometimes it freezes and sometimes all button are just greyed out. So the solution is... Dont cancell it unless you absolutely need to.
Okay, I have opened a separate issue on my issue list to thoroughly test this and fix it. Can you tell me if this problem occurs always at the same spot, like always if you cancel 3) analyse stars, or perhaps 4) register? The problem has to do with concurrency, so the specific behaviour of when it goes bad, can help me find the issue.
Hi @heylers, Thank you very much for your feedback.
Can you share with me what settings you use in 2) Calibrate? Is it defaults or do you enable/disable certain settings? Is it misbehaving when you push cancel at the start of calibration of later on? Please be as specific as you can, that will really help me to sort it out. It is very likely a concurrency issue, so that means it has to to with multi-threading and the moment that you push cancel during the calibration can really help me to find the issue in our code.
It's the default settings. Usually what happens is it starts and a say a few to maybe 15 seconds later (maybe at 30% or so?) I notice the calibration assignments aren't right. So insted of running it further, I cancel. It just stops there with "cancel" and everything greyed out and stays there.Â
@mabula-admin I have just worked it out - its when I am typing the file name - every time I press the space key in the name it is toggling the selection in the background 🤣
 Â
The reason the file is selected (sometimes) is that I occasionally like to view the calibrated image to get an idea of what it looks like before I perform the integration.
Please accept my apologies for missing this issue earlier. I have added it to the top of my issue list and will fix it as soon as possible. I will report back when it is fixed.

FIXED space bar can no longer deselect/select a frame in the frame list while entering a name in the Enter DeepSky object name field in 1)LOAD
Previously, if you have loaded a frame into the image viewer, and you would enter a name with spaces in the Enter DeepSky object name field in 1)LOAD, the space bar would toggle the frame in the frame list from selected to deselected or back. This is no longer the case and thus fixed.
@mabula-admin thank you very much. This was an incredibly annoying bug and one of the main reasons I stopped work on my high resolution full Milky Way project.

I have fixed the issue with the cancel button not working properly in 2) Calibrate, thank you very much for reporting this. The fix will be part of 2.0.0-beta38 which will soon be out.
