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.
I just installed APP 1.071 and it will not calibrate lights.Â
After loading lights and master flats, darks, and bias frames, when I hit "calibrate" I get the following error message:
========================
Encountered error in module:
LightFrameCalibration
Error message:
java.lang.ArrayIndexOutOfBoundsException: 1
Cause:
1
df.a(Unknown Source)
df.doInBackground(Unknown Source)
javax.swing.SwingWorker$1.call(SwingWorker.java:295)
java.util.concurrent.FutureTask.run(FutureTask.java:266)
=======================
I reloaded APP 1.070 and frames were calibrated as expected so the problem appears to be with APP 1.071.
One thought is that the master frames I am using were created with APP 1.070 - do I need to create new master frames?
Thanks!
Â
That shouldn't cause an issue no, when new master frames would be needed Mabula would make that a veeeery clear point. 🙂Â
This is a programming error, Java is notifying about it and it's something for @mabula-admin to have a look at. Thanks for sharing!
Hi @backroadrider (& @vincent-mod),
Masters of APP 1.070 should work in APP 1.071.
Can you please provide more information?
What settings do you use in 2) Calirbate and perhaps 0)Raw/FITS if needed?
What kind of data are you integrating ? is it color or monochrome data?
Kind regards,
Mabula
Hi @mabula-admin,
Thanks for your reply. Â
I have an idea that I have not been able to test. This problem started after I used the latest version of Pixinsight's SubframeSelector process to analyze and save the image files. It turns out the new process defaults to .xisf and also saves a thumbnail and some other "image information." I had to use PI's batch conversion tool to convert them back to .fit files and I am betting something got messed up along the way.Â
I am going to reprocess the original images and see if that solves the problem. I will report back.

Hi Steve @backroadrider,
Okay, thanks for the feedback.
Perhaps one of those PI fits frames gives a problem then. In the console window you should be able to pick out which frame give the problem. If you can find it, I will be happy to have a look at it.
APP will do frame selection for you by the way, there is no need to do this in PI.
From 3)-5) APP will report all analytical results like star density, FWHM, noise, SNR. Before starting an integration you can also plot these results with your right mouse button on the bottom panel with all frame information. Then you can simply decide which frames need to be disregarded if any. You can also sort the frames on these analytical results, like sort on FWHM 😉
Kind regards,
Mabula

Thanks Mabula, @mabula-admin
Thank you for the tips; I clearly need to spend much more time with your excellent software!!
All the best,
Steve
