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 team,
Loaded all my lights, darks, flats & dark flats as usual but for some reason whenever I reach step 5 it crashes and I get this message.
Encountered error in module: CalculateScaleInCropworker
Error Message
java.lang.NullpointerException
Cause:
null
s.a(unknown Source)
s.doInBackground (unknownSource)
javax.swing.Swingworker$1.call(swingworker.java.295)
java.util.concurrent.FutureTask.run(FutureTask.java:266)
I've run this four times on two different machines (macs) with the latest version of the App installed.
Very frustrating, can you help?
cheers
Andy
Sorry for the inconvenience. What APP version are you using?
@vincent-mod
Hi Vincent, as stated in my op, I’m using the latest version App 1.075
cheers
Ah right, I overlooked the "latest version" part. What I notice is that many crashes seem to be related to the data itself. Could you perhaps try this again without calibration data? And then add them separately to see which data is causing it? I can then ask you to upload that and will pass it on to Mabula.
Ok, took a while to get it done but it eventually worked. Seems a master dark flat was the issue. Good call to work through it that way. Thanks!
Superb! I think this is the cause many times, it would be nice if APP could somehow recognize this better, but at least you got it sorted. Interesting to know if you saw anything weird with that frame?
