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.
While attempting a really basic 2x2 mosaic and during the Registration process I'm getting a Java related error. I originally tried this mosaic by loading all my 40 subs (10 x 4 panels), OSC camera... really simple. I always got stuck in Registration about 80%. Sometimes I got an error with some recommendation that did really help. Then I processed all 4 panes individually having 4 integrated .fits files. I attempted to do the mosaic with just this 4 .fits and I got the java error. It seems that no matter what I cannot do a simple mosaic. Please see the screen shot with the java error attached. I'm running 2023-04-17: APP 2.0.0-beta17 in a Silicon M2 MAC.
The best way to process a mosaic, is to first create the mosaic panels (so you end up with 2 panels in the end). Then load these panels in again as lights and set APP up to perform the mosaic.
- Amount of stars to 1500
- Scale start to 5, scale stop to 10
- Dynamic distortion correction on (off if that creates weird artifacts)
- Same camera/optics off
- Registration mode to mosaic
- Normalization to advanced
Are you doing it this way already? If not, please try this.
@jberganzooutlook-com, thank you for confirming it did work after several tries. Can you share which setting adjustment made it work?
