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.
Obviously, I must be doing something incorrectly. Both the NGC 292 tutorial images as well as my test images end up- with the result being in Monochrome. Obviously I am missing a step somewhere, but where mystifies me. I have tried this three times now. Platform Windows 11, 64 gb memory, 4 tb storage, i9-13900 proc. APP 2.0 beta 36.
Thank you for your help.
Hi David @waterman,
Thank you very much for your question and welcome to the APP forum !
Do I understand correctly that when you combine the the different L,R,G,B filters into a composite in the RGB Combine Tool that the result is still in black and white? If so, maybe you need to turn on color saturation in the preview fitler on the right side? Did you try that?
In this part:
At 2min and 40 seconds, if you do not see color on your computer monitor, you might need to enable the saturation checkbox on the right side and increase the saturation slider to 0.25 and lower sat.th slider to about 10. Do you see color then?
If this solves it, your computer monitor probably is not setup ideally to show the sRGB colors, some manual configuration of your monitor color color temperature, saturation, contrast can also help then in this aspect.
Please let me know if this solves it and/or if you have any other questions.
