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 Mabula,
im Testing APP and i like to know whats possible with my M31 Data.
I try the Software and its very good, better than DSS. The Colours are much better, but the Star Colour Tool is a bit complicated, for me :-).
Maybe you give my Data a try.
Here is the Link: removed link
Sorry for my English, im from Germany, i hope its okay.
I take the Lights with my Canon EOS1000DA, a 150/750 Skywatcher PDS Newton and my H-EQ5 Pro Mount.
I dont take Darks, because im Dithering. The Question is, what Settings works best with Dithering? I use Sigma Clipping with Kappa 2 and 3 Itherations. I try many but only with these Settings, i dont get the typical Pixels in the Image. You know, what i mean?
A Esprit 80 ED Triplet is on the Way, so i can handle larger Nebula and M31 in the future.
Maybe you let me know your Workflow. I think i buy the Software :-).
Thanks and Greetings, Markus
Gutentag Markus,
Sorry for the huge delay, Mabula was on a holiday during this time and I happened to be extremely busy as well. 🙁 You can check some workflows in the Video tutorials section on top of the site.
