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: On the question of the reduction of the noise made in lack, or I do not find, a specific tool that allows to treat the final noise of the image, the Calibrated Background helps in the reduction of the noise ...? Thank you.
Hi @carlesa25,
A tool for noise reduction is not yet present, but I will introduce this soon 😉
I intend on noise reduction that you can control on several scales. This will also apply for a separate sharpening tool, which will come as well.

Hi Mabula, here too I would be very interested in this feature. Do you already have an approximate idea on when this feature will become available?Â
All the best Frank
Hi Frank @foschmitz,
Will try to include it in 1.060 (which will be a big ugrade !), otherwise it will be 1.061 😉
Cheers,
Mabula
Hi Mabula,
I loaded the 30 day trial about three weeks ago, and about to purchase, and still have not seen an announcement concerning a noise reduction tool, sharpening tool or potentially masks (in work flow, after integration and registration, after combine or to utilize after stretching just prior to taking non-linear and possibly again after non-linear.
Is this upgrade going to be made available soon or has it just recently been released?
Thanks,
CJ
Hi CJ @explorer7377,
Sharpening is part of the preview filter on the right already 😉
But a special and separate sharpening/smoothing tool will come and also noise reduction and deconvolution.
I will try to introduce these new features soon and step by step. ( my ToDo is very extensive in this regard ).
Kind regards,
Mabula
Mabula,
I'm sure the list grows daily! No worries as you are doing a great job getting this tweaked. I am a huge fan of the program and cannot wait to see what comes next!
