Jan 31 2026: APP 2.0.0-beta40 will soon be released with many fixes especially for Linux, upgraded development platform and 10-20% performance boost !
Jan 15 2026: FIXED LICENSE SERVER VPN Tunnel issue
 The issue could have prevented APP to start when using a VPN tunnel or another complicated network configuration, like using APP on a remote computer on a different continent. This issue is fixed now and APP should start normally.
Jan 04 2026: Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version. Unfortunately, Mabula was struck by a severe flu virus in the past couple of weeks and thus could not work. He is getting much better now and he has resumed work to release 2.0.0 as soon as possible. Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Nov 28 2025:Â APP 2.0.0-beta39 has been released !
Hello folks!
Today I tested the new version of APP and tried to edit a picture completely with it.
I am very impressed with the new features like the Star Reducer Tool!
Â
Edited in APP only:
Â
Â
APP + Photoshop (HLVG + a breeze of Topaz DeNoise)
Â
Â
I am very satisfied with the results and I am sure that the green cast in the first picture can also be eliminated even better in APP.
I think the test was successful 🙂

Thx Mabula & Vincent 🙂 @mabula-admin @vincent-mod
This is a test to show what APP can do. In a forum it was discussed whether APP or PI is better for creating astro images. I then tried to show what is possible with APP alone.

Nice image and process. I am also enjoying APP only processing. As an OSc imager, looking back at some data it becomes more natural and better balanced without additional Ps editing. I have found some neat tricks to deal with green cast in star color calibration and HSL selective color mods that might be useful. almost similar to HLVG.
The first is the magenta-green sliders for the color-color plots in star color calibration, which can help with initial green bias, and the second is the HSL selective tool where the green color is selected from 0 - 100% (all pixels), and then the green-magenta slider is moved fromm 40-70% magenta, while reducing saturation from -20 to -50% or so. These two sliders need to be carefully checked so no magenta artefacts appear around stars so there is some iterations. Carefully done, it works very well. Maybe @mabula-admin and the team know how to fine tune this a little better.

Hello Colm!

I also really like the "APP-only" results. As you say, the pictures look very natural.
Thank you for your input. Maybe one day there will be a "one click"- solution in APP similar to HLVG. That would be a development idea for @mabula-admin 🙂 .
