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.
Hi,
Often I use Alias / shorcut for Bias, Flats or Dark files. These files are often shared between acquisitions. As such, I create Alias directories (Shortcuts) within a specific directory.
For example: Last night I tool M81 and M63 with the same equipment profile and filters. At the end, I created Flat, Bias and Dark for M63. Each of them are in a directory within the M63 directory. On the M81 directory I make Aliases directory that opens up the M63 ones.
The problem is that I dont see these Alias directory under APP when I "1) LOAD" my files. Its hard to explain. :). I'm hoping you get my point.

Yes I totally get it, I think you're the first one using it like that. 😉 But I can see the benefit, I would have to ask Mabula if this is possible, I'll get back to you on that.
I just checked locally on my Mac and for me it works. What I did was creating a "symlink" for the directory I wanted to link in to my working directory from the Console.
It shows up as normal directory in the file dialog in APP.
What is not working is using an Alias created in Finder, because Finder creates only a MacOS specific proprietary file pointing to the destination by the content of that file instead of a POSIX compatible symlink.

Ah, very interesting Mario thank you for that! I didn't know this was different from a regular symlink.
Ahhhh yes, learning. I just downloaded a small app that allows you to create Symlink without the use of the terminal and it works perfectly! Thank you Mario.
