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,
Based on my notes during use of the APP, I have prepared a short description for beginners in my native language. I know there is such a need in my country, among my fellow countrymen. Below is direct link to tutorial I've made.
Witajcie,
Podczas użytkowania APP, pobocznie uzbierało mi się bardzo dużo notatek, z których przygotowałem krótki tutorial jak w najprostszy sposób wywołać zdjęcia, bez nadmiaru potrzebnej wiedzy o szczegółach. Opis powstał w odpowiedzi na sygnalizowaną potrzebę od wielu osób, z którymi rozmawiałem na temat APP. Mam nadzieję, że przyda się.

I did also English version, available here: http://www.astrofoto.pekdar.net/en/2070/
Please be aware that English is not my native language. I did my best. If you know where I should rewrite some sentences wit best English, please PM me. I'll be very grateful. I'm also aware that there are better tutorials with English over net. But maybe one more, will be for somebody also useful.
Edited by Mabula: I have made this a sticky for our Polish users 🙂
New website with new address. The old links will stop works at 30 Sep. this year.
