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.
Thanks for finding this little quirk. Now I know what happened to me on several occasions, probably a strange symbol from ascii code on the keyboard maybe, or the use of accents on letters (I don't know or didn't check this however).
@vincent-mod Thank you ! I think this problem not only cause by Chinese symbol, but also Japanese symbol. Maybe all non-English symbols can cause this. But for "~!@#$%^" these can type by English input won't affected.
Thank you very much for reporting this issue. It must be related to charachter encoding of the input for the deepsky object. I will test this and fix it 😉
Could you test if you see the same behaviour if you type a chinese/japanese character for the object in APP 1.083-beta2 ? The interface problem seems related to a bug that was fixed in beta2. So it will be interesting to see if the problem is not there in beta2 😉
Thank you for reply Mr. @mabula-admin . I had already tested in 1.083beta2, and both language symbol did not cause any crashes and can save as filename very well. Thank you for fix it and update! Hope the official version will release soon. JieLin
