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 !
Hi,
Just integrating my images from last night, all channels come out fine except Ha, which is showing weird crosses.
I've checked every sub and they are all fine. I've also checked the Ha Flat - which is fine. OIII, SII and IDAS integrate fine (using same master dark, bias, bad pixel map and flat dark.
I get the same issue with both objects I observed last night.
Any pointers to what might be wrong?
Here is a clip of the integrated image - every star is a cross
and one of the RAWs (same view parameters)
Â
Any help really appreciated.
Simon.
That is interesting. Sorry it took a while, I had an issue with the forum login.
I think I would need some of the data to be able to see what is going on exactly.
If you can please upload some of the relevant subs to our server;
Go to https://upload.astropixelprocessor.com and use upload1 (or upload2 till 5) as username and password will then be the same as the username.
Create a directory named “simontelescopium-crosses” and upload in there. Thank you!
