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 APP, I got my trial started last night and have started processing some data! I am relatively new to Astrophotography (3 months in) and am hooked for life!
My setup is as follows:
- ZWO ASI294MC Pro cooled camera
- Explore scientific 127mm APO refractor with Moonlite motorized focuser
- Skywatcher EQ6R Pro mount
- Guidescope and Orion Starshoot Autoguide camera
When I load all my data (lights, flats and darks) and check all my options the image comes out monochrome now matter what I try. When I try to use the color correction options on tab 9 I get an error that I must load RGB data to continue. I have tried with and without the force CFA option to no avail. Any tips would be appreciated. When I stack this data in DSS or PI they come out with color as expected. I can try to provide anything you need to look at just let me know.
Thanks,
Charles
Hi Charles,
i have the same camera and was able to process it successfully. Besides force CFA you might try putting RGGB in the debayer pattern, although I don’t think I needed to do that. Which color tool gave you the problem?

Sure you put on the force CFA flag in step 0 before proceeding to the rest? It works for my ASI183MC.
I tried two more stacks with mostly the same data last night and made sure that force was checked. These stacks came out with color no problem! I thought I had it checked in the first two but must not have. Thanks for the quick reply!
