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,
Recently bought the owners licence and now doing my first stacking after getting some new data and installing the owners licence.
When i try to save the image with or without stretch and in JPEG or in TIFF i get the following message:
Encountered error in module:
TiffImageSaver
Error message:
java.lang.IllegalStateException: output == null!
Cause:
output == null!
it.geosolutions.imageioimpl.plugins.tiff.TIFFImageWriter.write(TIFFImageWriter.java:2654)

Could you please help with what i should do?
Thanks!
Rick
Hi Rick and thank you for the purchase!
Sorry for the inconvenience here, could you check if the location you are saving to is able to be written to? On what system is this?
Hi Vincent,
No problem of course.
The odd things is that the FITS files save without any problem (the automatic ones and the ones with the save button) but when trying to save manually as JPEG or TIFF it gives the error.
I have since tried to copy the data elseware and try it again, but this gives the same error.
The loading bar goes to 11%, 35%, back to 11% and then pops the error.
Would be great to know what i can try to do about this as i do not have software able to process the FITS files.
Thanks,
Rick

Ah, interesting, what APP version is this on? If you're not using 1.083-beta, please try that one first. I'm wondering why the output in those cases causes a nullpointer, you indeed are pointing it to your working directory right? And any weird characters in the name perhaps (not that it should matter I think)? Is this on an external drive?
Version 1.082, this was the download that was linked in the purchase email. I have just downloaded the beta files, and will try after this process is done. I have moved all the files to a different location and doing the whole stacking process again, to see if it somehow has something to do with the files it was located in. I am pointing at the working directory yes, i did not change this. No weird characters, and not an external drive. I will let you know if 1.083 does work, should you think of anything please let me know so i can avoid installing the beta 🙂Â
The beta is fully working without any major issues so that will be fine to have as your regular build. Please keep me updated and if all else fails I'll inform Mabula for more suggestions. Again, I do apologize as it would be nice to have a smoother start. 😉
Thanks, Will do. The odd thing is that i did not have this issue with the trial version a few days ago. Will keep you posted.
That is interesting as they should be the same, which might point to something going on on your system perhaps? Anyway, let's wait for your tests.
I have just tried again from the new location an had the same issue, only after it popped up i also received a notification from my AVG Antivirus software if i wanted to allow APP to write to this "protected" location. I allowed this, and then i could save as usual, and also tried again from the original location and that also seems to be working. Somehow it had something to do with it, even though the AVG message did not pop up earlier. Thanks for the help!
Ah, antivirus protection. Yes, that's indeed something that can cause issues, they are not always responding correctly to system activities. Nice to have found out! I'll keep it in mind as well if people experience this.
Same issue, AntiVirus turned off and Tiff saves... probably need some kind of whitelist action on it.
@jjones Yeah looks like the same issue. I guess i was lucky to get a notification from the antivirus after many tries. Hope it works out!
