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.
Hi,
Thank you for the recent change that brought the ability to keep image viewer docked! I am now able to use the program again!
I still think the old (1.08x) layout has better space utilization!
I am having hard time seeing the text and the selection green rectangles, especially when remoting into my main computer as they changed from thick bold in previous versions to really thin; is there any way to make them bold?
Â
Thank you very much!
Jay
The fonts are the same actually, do they look the same when you start APP (both old and new) on your local machine?
@vincent-mod Thank you for your prompt response!
They look small on the new version, the selection lines are thinner too!
Please see the attached pictures.
Thank you!
Jay

I don't think I'm seeing the same thing. Did you check locally? Via a remote setup it may possibly have a different cause.
Also tried some select boxes, but they also seem the same. It's as if you have 2 different resolutions or something.

Old:
@vincent-mod I ran both programs, old and new! The difference is clear on the selection green lines. I checked it directly on my main computer. The green lines get difficult to see when remoting in to the computer, but still much thinner than the old version as you can see in the attached.
Thank you very much for taking the time and checking this for me, I really appreciate it!
No problem, if it is an issue, we want to see if we can fix that. 🙂 But on the screenshots above I took, do you see the difference? Because I can't really, that would indicate it's a local issue somehow. Can you tell me what version of APP you are comparing and what OS you're using?
@vincent-mod ,
I ran 1.083v4 vs v2b2
here is a screen shot from both, they were running at the same time.

And can you tell me what machine, OS and screen resolution you're using?
It's strange, let me forward this to Mabula. He has been sick so please allow for a few days.

Super, thanks for the info!
One thing I'm wondering. Do you see the same if you switch off OpenGL? Press the green OpenGL button on top of APP.
@vincent-mod You found the issue! It is different when openGL is on or off!
It seems that it is on by default on one version but off on the other? So, if openGL is green, that means its on, right?
Green is on yes. It may very well be desktop scaling as well, do you know if you have that on? Mabula is going to investigate it at least.
@vincent-mod Here is what I have:
Â
What happens when you switch the "Let windows fix the scaling" off?
@vincent-mod It did not affect the result.
Hi Jay @zurgany,
I think the issue somehow has to do with you remoting, like you say, to your main computer.
The code for drawing of the boxes has not changed between 1.083 to 2.0, so maybe our new development platform reacts differently when you make a remote desktop connection which I am assuming that you are referring to with "remoting"?
Is OpenGL on or off when you remote? In which case are the lines okay, with OpenGL green/enabled or with the CPU image viewer?
Mabula
@mabula-admin Hi Mabula,
The lines are thick with OpenGL, but thin with cpu.
They are thin whether remote or direct on the computer. The program (V2B2)defaults to CPU every time it starts, while the older version stays at OpenGL.
The boxes get really thin without OpenGL on!
Thank you very much for your response!
Jay
Could it be a gfx driver issue? Sometimes we see people have both Intel and Nvidia drivers which are not set up correctly, they get it fixed by looking at the settings for those, maybe set it to nvidia specifically in the settings?

Hi Jay,
Thank you for your response. The 2.0.0-beta2 version will remember the state of CPU/OpenGL between restarts. But if the computer does not support OpenGL, then CPU is the only option of course.
I have made a note to increase the line width for the cpu image viewer, I think I can fix that 😉
What i don't know yet, is the behaviour different whether your use APP with remote desktop or not?
