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 wanted to add frames to a mosaic, but I'm getting this "java.lang.IllegalArgumentException" error, and I can't figure out what's going on. Mosaic using the Sigma 135 / ASI6200MC lens, total is 11 frames. I've already made another mosaic with the same setup of 14 frames, and it "worked" correctly.
Does anyone know the cause of the problem?
Thanks in advance 🙂

Hi Breard @bilko29,
Thank you very much for posting your issue and welcome to the APP forum !
That error seems to indicate a problem with writing data to your Working Directory location. With regular internal hard disks, this issue should never happen. Could it be that you have your working directory on an external drive or network, and that the connection could be lost to the external hard disk or network share?
Also, is this error repeatable? Does it happen each time, or did it only occur once? If only once, I think something went wrong with the connection to the harddisk on which the Working directory is.
It would be helpful to understand why this error occurred, so please share as much information as you can. I will try to catch this problem and warn the user about the issue or prevent it from happening.

Thank you for your feedback. This error only appears on the "6" tab - Integration. And with this product, when I add a frame to 13 frames, the integration goes well. I add another frame and then I get this error.
And I've had this error since I upgraded to the latest stable version.
I also tested it on another hard drive, same problem.
Hello,
I'm still having this problem.
Error message:
java.lang.IllegalArgumentException: capacity < 0: (-1884069752 < 0)
On a mosaic of 9 frames, up to 8 frames are no problems.
Are the numbers indicated in the error (-1884069752) bytes?
I tested it on standard internal hard drives or SSD
thank you for your feedback 🙂

I had the same problem with 24 panel mosaic, I have enough of RAM (128GB) and disk space (TBs) so this is not an issue.
This happens with a local NVME disk, I have plenty of space there, there is no write permission issue. I can reproduce it every time.

I decided to upgrade to the beta39 and now I get this, happened during LNC processing.

I have downgraded APP to 2.0.0-beta30, and I am able to register and integrate the mosaic just fine, it is a clearly a regression then.
If you want I can send you the FITS files so you can take a look.
merci pour ce retour, j'étais aussi repassé sous le version XX3.0 fin de créer ma mosaïque de la constellation du Cygne
demain j’installerais cette nouvelle version 2.0.0-beta39

Hi Breard @bilko29,
Wow, that looks really awesome, great work !
2.0.0-beta39 is not yet released, sorry for the confusion, it will be released within 7-14 days for sure !

Looking at the thread itself, I also started to get this error, but only on some Seestar related files. However, reading about the beta 39 changes, it really sounds like it holds major upgrades and it sparked my interest, so the question is, how far from the release is @Mabula?!
I also run into the same error while integrating a mosaic with 3 new panels.
Previously I was able to integrate successfully (before the new 3 panels) but now this error occured.
I guess we'll have to wait for the beta 39 🙂
Greetings,
Pavel
