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.
Ciao,
here is my first shoot with a DSRL without eq mount (during holidays you have to balance between the number of the suitcases that your wife want to carry and your equipment ... :-|)
The first one is the MilkyWay (EOS 80D - Tokina 11-20 F2.8 (IF) DX - F2,8 E6s I3600 - 34 Lights and 30 Darks)
Strange artefacts in the bottom right of the image
The second one is part of Cassiopea and a little M31 (EOS 6D - Canon 50 F1.4 USM - F5,6 E3,2s I1600 - 32 Lights, 15 Darks and 15 Bias)
Strange artefacts at the top of the image and strange lines from left to bottom right
All were elaborated only with APP and I really appreciate if someone would like to redo the elaboration (while I'm used with Affinity Photo I'm not used at all with the post processing tools of APP ...)
Here are the links to the stacked images:
Dropbox File (Private or Invalid)
as soon as I can I'll share also the stacked image for M31Â
Maybe this evening let's try M31 with a 200mm lens ... which means about 1s per shoot ... maybe something will be visible 🙂

Best,

Hi L.
The top one is, I think, just some gradient in the data. The second looks to be a data issue. I'll try to download (Dropbox doesn't work great here usually) and have a look.
Ok, had a look at your dropbox file (was only 1), I see the weird artefact there. That's in the data, so it must be something like possible light leakage or reflection etc.
Ciao Vincent,
thanks, i'll check all the files one by one; yep only one file, internet connectivity it's too slow from here (the fits after integration).
This one is cropped and a little bit elaborated (maybe too stretched).
Best,
Luciano
