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 đŸ™‚
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.

Astro Pixel Processor 1.034.2
- FIXED problem with FITS data which has a forward slash "/" in the isntrument name. Gave problem with saving the calibration frames (André en Roberto possibly? )
- CHANGED New adjustments in memory management, this should reduce the slowing down of the application when it does a long stack task.
- SPEED Implemented an optimization in the stacker for 32bits data, which should speed it up somewhat.
- IMPROVEMENT Implemented an out of memory protection for all stack compositions combined with integration scale factors (important for big mosaics). By rescaling the mosaic so it stays within memory limits, the user can at least make the integration if he has too little memory in his system for the chosen scale.
- FIXED removed memory leak in stacker, now bigger stacks are possible without throwing a out of memory exception.
- IMPROVEMENT optimized data conversion for 32bits float data being send to image viewer
- FIXED LNC can be properly cancelled now, popup window doesn't stay alive
- FIXED metadata is cleared as well when CLEAN button is pushed in 1)LOAD
- IMPROVEMENT The weight file map is gone for normal itegration!, will only be there in case of drizzle/bayer drizzle because all pixels will have different weights due to the drizzle technique. This should speed up integration of non-drizzle stacks significantly.
- FIXED reported needed HDD stack space is now correct when drizzle is used.
- IMPROVEMENT image viewer memory is cleared from old image data when a new image is being loaded from the file list.
