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 guys...
The season has started and I tried to process my first EDGE 9,25 image when a strange error message poped up in the calibration sequence (it seems as the error occurs when the program reached the "Analyse Stars" process) in APP v. 1.083 beta2, (see attachment). I tried a few times with different data, but same message. Help to proceed is much needed and appreciated....
best wishes

@ajnilsen It turns out that the star analysis in 1.083-beta2 not always is very stable. Please try 1.083-beta1 and see if that goes well.
Hi... Many thanks for your suggestion!
I rolled back to ver 1.082 and tried again, but same error message. Strange, it worked last week both with 1.082 and 1.083 beta2....?
I am stocked 🙁

I restarted and tried again, but still error. The message appears just as the "analyse stars" process begins. Could it vhave something to do with Windows (Microsoft) blocking java for security reasons?
AJ
Hi again...
I did a test with an image om M13 taken a few nights back, but with another camera (ASI2600c). This works normally in APP (v 1.082) applying flats and darks and going through analyse stars. The error appears when I process files taken with ASI533c. I use Astro Photography Tool (ver 3.88.3) for obtaining the images on both data sets, but two different computers (both PCs). Never had this problem before with the same set ups. I am attaching one image file and one flat filed for the data set that does not work (M57)...
No I am even more lost 🙁
Alf J.
@ajnilsen Hi again. Sorry to see your issues continue.I downloaded the two files and they look good to me.
Could you upload the ASI533MC data set to
https://upload.astropixelprocessor.com/
using upload for both username and password? Please create a directory called ajnilsen_analyse_stars_error and put the files in there. Then I will have a look (probably on Monday) to see if I can figure out what's wrong.
Fine...
I am uploading 10 light files, 10 flats, one master dark. I have a suspecion that the problem could be related to master frames). I shall be away for the week end, but I'll be back on Monday. Uploading now.... Please let me know what you can track... Thanks!
best
AJ
Hi, Yes I do and I just now made a new master dark from the old RAW darks and now it seems to work..... I'll let you know how it turns out at the end. Thanks for your help so far.
AJ
Hi again....
The error message is linked to the master dark. When I generated a new master dark form the same raw data (March -21), the process worked. The funny thing is that the "corrupt" MD-filed works with other data sets... anyway, problem solved 🙂
best wishes
