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.
Running MAC Ventura 13.1 on an M1 Mac. APP 2.0 Beta13. Ran a 4 panel mosaic which took 5 days to integrate. Then on loading final Integrated image JAVA error failure. APP crashed out and I lost all data in original process. On loading only the final Integrated image the same thing happened twice. Cannot load image at all in APP. I have copied the error process to notepad and can upload if required.
Hi @rsbuckell,
That sounds like the resulting image is too big in image dimensions and you are getting an out of memory crash probably. Do you have any idea how large the integrated file is? What focal length was used?
If it took 5 days, then you are creating the mosaic not according to our recommendations here:

The most efficient and most robust way to register any data set as a mosaic is to first integrate the individual mosaic panels. Then register the mosaic using only the individual integrated panels. This holds for other mosaics as well. Don’t try to create a mosaic out of 100s of indivdual frames. First create the mosaic panels.
If you did, and it still took 5 days, then something must be way off in terms of APP being able to register the frames correctly. In that case, did you try different settings in 4) Register?

Many thanks for the fast reply. The total size of the final image was 1.6GB. I simply cleared the data and reloaded the final integration and in v1.075 without any issues and it was complete. I didn't follow the tutorial though and will give that a go and report back if necessary.
It may be a good idea to update to our latest beta version (you can find it on top of the forum). This is way faster and has better memory management.
