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,
 I'm reviewing APP's capabilities but haven't been able to determine if it can remove blooms from a NABG camera using the KAF-3200 CCD. The closest I have seen is the option to remove hot pixel columns, but a bloom likely would not fit in that category.Â
Thank You,
Mike
Could you post a screenshot so I know for sure what you mean with bloom? 😉 (to clarify, just so I know for sure we're talking about the same thing)
Attached is a JPG example.Â

Thank You,
Mike
Ah excellent, thank you. Yes that is something APP can't really do at the moment. But Mabula is working hard to add a feature for that as this is also an issue we want APP to solve on some instruments from iTelescope.
OK..that's understandable. In the meantime would I be able to calibrate & remove the blooms (I am using CCDStack), save the calibrated frames then import them into APP to continue the processing?

Thank You,
Mike
I don't have experience for that myself, but what I would do is to calibrate the frames in APP, save the calibrated frames (down on the calibration tab) and then process it through something like CCDStack. However, it will depend on how that software is saving the results again. I've seen quite some software not properly handling fits headers, which can be problematic when you want to continue in APP again. If possible I would save the results in CCDstack and make the integration again in APP.
