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.
Hi I am trying to produce a BPM which I have done many times before using a different ccd. I am now using a asi183mc and have tried to calibrate the darks and flats using RGGB, Adaptive Airy Disc and force Bayer CFA. I have also tried it without these checked. Every time I get the same error message. I have rebooted the Pc win 10, ver 1809 64 bit os. I have also taken new flats and tried again several more times
I tried with just flats and darks to make a bpm and then lights flats darks bias and the error message comes as it tried to produce the bmp.
I have unticked bmp and it actually produced a MD, MF,and MB.
Any help would be appreciated.
Kind Regards Jenny King
So if i understand this right ? all you want is to create the Masters right ?
MF, MD, MB, BPM.
Why are you using Master Bias on a ASi-183MC IMX sony Bsi chip?
Mitch
Because I tried using a dark flat and it seemed that the calibration files were not applied. Plus I don't actually know much about the chips. Any advice for this chip would be appreciated. My other astro cameras are ccd mono but I thought I would give this MC a go as weather often restricts time of imaging in my location.
Jenny
Hi Jenny, its the same chip as my Altair Astro 183IMX Color.
So that should not be a concern, something else is going on here.
create 32 bit masters is unchecked..
Are you in the UK or USA?
i teach Pixinsight , and SGP , APT to students all over the world via Anydesk.exe.
been using APP bout a year now ,,, no longer use PI for calibration only processing.
i could have a quick look , if your not sensitive to logons onto your PC.

I have just added a coma corrector to my 200p so I am going to start again with lights darks flats and flatdarks and see what happens. I am in the UK. I don't use pixinsight. I have used sgp since it was free! And have successfully used APP for quite sometime but with a qsi690 mono and an Atik314l mono. Usually with a TS 71 imaging star. The amp glow on this ASI 183mc is something else and I bought it to go on the 200p for galaxy season which from where my obs is, is now. I will see how I get on with some new data.
Thanks for the offer and I might take you up on it once I get some data and clear skies.
Hi Jenny,
I don't think that it is something that you are or are not doing, I am getting similar Java errors myself, see: https://www.astropixelprocessor.com/community/main-forum/yet-more-issues-that-i-have-no-idea-how-to-fix/#post-5968
There are many more reports of similar issues throughout the forum too.

Yes , just like th AA183MC the right hand side Electroluminescent starburst can be cleaned up in APP and a good set of darks (30-50)
the amp glow is actually on top and bottom and is very low.
