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 all Â
I am new to APP (trial). I have Sony A7rii and therefore using 16bit TIFF files (~240MB) converted from uncompressed .ARW. These files load into APP but I get java outofmemory errors on calibration or analyse stars, even with small numbers of subs. I am asking at this stage whether such files should be OK in APP, before perservering further with settings. (Desktop i7, 16GB,windows 10) (These files process OK in Nebulosity 4, but not DSS 3.4.4)Â
Thanks
Peter

Hi Peter,
Thank you for your question and welcome to the APP forum 😉
The files should be okay, you only need to configure APP to use more memory than the initial configured amount of 2GB. Check this topic on how to do this:
https://www.astropixelprocessor.com/community/faq/how-much-memory-should-i-allocate-to-app/
So with your 16GB of memory and windows 10, I would set the amount of memory that APP can use to 12-15GBs. Leaving 1 -4 GBs of memory to spare to let Windows 10 function properly 😉
Your files shouldn't need more than 4GB of memory for APP to function without out of memory exceptions to occur, unless you are starting to make big mosaics. Then more memory is required.
Let me know if you can process the Tiffs fine now 😉
Sony RAW support will come by the way, working on it.

Thanks for that 😊 . Yes, started working immediately after increasing the RAM. Now getting to grips with your great program. Looking forward to sony raw handling.
Excellent Peter 😉
