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,
this is my frist stack using APP - I was formerly using Deep Sky Stacker.
DSS failed to do a perfect align in the corners, since I was using the lens at f/2.8 (star quality not perfectly round in the corners).
APP aligned everything perfectly, which was the reason I purchased this software.
I believe everybody giving APP a try should use the most troublesome images for stacking and see for the results.
About the picture:
Nikon D750 with Sigma Art 135mm, f/1.8
Tracking with Astrotrac, post processing with APP and Photoshop.
Stack of 100 exposures of 2 minutes each at ISO 800 and f/2.8.
I took the exposures during 2 nights in 2017 in rural Upper Austria.
Hope you like it!
Best regards!
Chris
PS: The picture was stacked using LNC and maybe it looks just a bit too flat. I will probably try again disabeling LNC.

Oh that looks lovely! Thanks for giving APP a go and liking it. 🙂
