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.
Hello. Im having problems since downloading the latest version. I cant get the image to show in the image viewer. there are now two tabs above the image viewer window that didnt used to be there, but no matter which i select I still get no image.
Im also having issues running out of memory despite having a new 2Tb M.2 installed. I had hoped that would fix the issue.
Â
Please try and simplify any reponses please, as Im rather new to computers.
Â
Thank you-Â
Ryder
No problem, everyone can ask questions on any level. 🙂
There is a difference between memory and the amount of disk space you have. You're talking about a 2TB M.2 drive, which is disk space. Memory is a fast way to store and retrieve data, but is not permanent, it's used mainly for programs to run in and store data to work on and if required, save that to disk if needed.
Do you know how much memory your computer has? This usually is something like 8, 16 or 32 GB.
@vincent-mod thank you for the reply. I currently have 16gb but I suspect that may be the problem by what I can work out, and what I'm reading. So I have a 64gb upgrade on the way that I'll be installing hopefully tomorrow or the next day depending on delivery times. Would you suggest this should fix my issue?Â
Â
Thank you again for the reply and explanation 🙂
I would not just buy hardware straight away though. 🙂 16GB should be ok and I think you may have a different issue. Could you check to see what happens if you click on the OpenGL green button? On top of the APP window.
64GB is nice to have though in any case.
@vincent-mod I have upgraded to 64gb and it finishes the stacking without running out of memory, but still no image in the image viewer at the end. Iclicked the open GL green button and it now says CPU in yellow.
@vincent-mod oh and the tab says Open GL4 before I click it.
FOUND IT!Â
Â
I've finally found the image.Â
There is now a 'side bar' to the right that needs to be dragged open like a curtain.Â
I never had to do that on the older version of APP I was using.
Could you show a screenshot of that? I'm not sure what you are referring to.
@vincent-mod it's not the best image but I've circled in red the 'sliding side bar' that reveals the image.
Â
It's half way open so to speak in the image.
Ah, the console window is rather big. You can also click on those tiny arrows in the side bar to move it out of the way. I think we may have to look at how this works and improve that.
