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,
sorry but this is a mixed (APP & PI) topic...
in order to remove banding artefacts of my Canon 6D I proceeded as follows:
- In APP I did all the main processing (MB, MF, MDF, MD...Integration)
- In Pixinsight I did the 90° rotation + CanonbandingReduction + 90° derotation of the LightFrames + MB, MF, MDF, MD:
- 1. process PI: Fast Rotation 90 deg. clockwise, extension: FITS
- 2. process PI: CBR with default settings
- 3. process PI: Rotation 90 deg. counterclockwise
Then I processed all those Frames in APP: the resulting Integration is gray.
I checked "CFA" + RGGB in APP
My first integration (without Rot / CBR / Derot) in APP was as expected: colour but banding
the corrected frames (after Rot / CBR / Derot) do all have colour.
Any ideas?
thanks, Peter
@peter-s Hi Peter,
Have you tried loading the integrated (and therefore color) image into PI and remove the Canon banding from that image? Touching the raw data usually is a recipe for trouble.
HTH, Wouter
Hi Wouter,
thank you - no, not until now; I wanted to try with a "clean stack".. and my impression was that the caibration frames, especially the Master Bias induced the most of the banding.
I´ll try the banding reduction a) with the L integration, calibrated by the untreated calibration master files
and b) with with the L integration, calibrated by banding corrected calibration master files
as I am not the only one using a Canon camera = the CanonBandingReduction I´d be interested how do others proceed...
Peter
@peter-s Hi Peter,
Try only option a please. Option b will fail. Once more, don't modify raw data. Any raw data.
Wouter
