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'm getting this Java error in recent days with either 1.082 or 1.083-beta1. It doesn't seem to matter what settings I use for the TIFF. 8-bit, 16-bit, 32-bit float, different ICC pallets. All the same. Any input welcome.

Ok, I'm getting the same sort of error with JPEG as well.
@tschuh Do you get the error as well when saving to FITS? Is your working folder on the internal hard drive or an external one? If external, what type is it? Normal HD or SSD?
@tschuh So you probably get this error after processing a FITS file in APP, correct? Can you explain exactly what steps you do to get to this error and upload the FITS file that was used to
https://upload.astropixelprocessor.com/
using upload1 as both username and password? Please create a folder called tschuh_tiff_error and put the FITS file in there. Then we will have a look.
@wvreeven I was about to upload my FITS when I figured out what the problem was. My A/V software (Avast) was *silently* blocking not the fwrite() but the APP application itself. A recent update made that block more vocal and it was highlighted as a blocked application, false positive for ransomware of all things. I've whitelisted the app and all appears to be working correctly again.
