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!
Thanks for the awesome work with the Beta1 with Comet register feature.
It was a pleasure to test this update of yours and the outcome was even better than from any other software I have tested so far.
I have tested PixInsight, DSS latest beta etc etc whatever is out there and none of them could fix the comet without destroying it.
462 x 2s ISO 12800 + all bias, darks and flats (probably around 100 more images).
I live in the unfortunate area of Lat 59° N (southwest of Stockholm, Sweden) where the sky still was bright blue when Neowise was appearing in the sky.
Having the European highway (E4/E20) northbound popping with light pollution made these shots almost impossible to take, but thanks to your LP reduce feature in the Tool Section I was able to get rid off most of it from the final image.
Enhanced and edited in Photoshop CC 2020 with minor steps without destroying the image itself and this is the result of my contribution:
Keep up the good work and can't wait to get the 2nd update of this Comet registration!
