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.
Why would I get mono output fro0ma OSC camera?

This appears to have nothing to do with APP. You haven't provided a lot of information, but it looks to me as if at least some of your flats, darkflats and possibly lights do not have their fits headers correctly identified by filter type in your acquisition software. This could possibly be true even if you have not used a filter at all.
You may be able to use APP to override the fits headers by explicity specifying a filter in load. I would suggest selecting multi channel filter processing on the load panel, and when it asks for a filter type select rgb. You would need to do this for all lights, flats and darkflats.
good luck

Hi Trevor @woldsweather,
Thank you very much for your question. John @connor231, thanks for the help 😉
If the data is OSC and APP does not recognize that automatically, the image files probably lack correct metadata to indicate that it is OSC data with a CFA pattern that needs to be demosaiced/debayered.
You can tell APP to force debayering with 0) Color Settings, force Bayer/X-Trans CFA. Then the result will be in color and the automatic filter assignment will be RGB instead of MONO.
Were you able to solve this in the mean time, or do you need assistance?
