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 Admin,
I have used a Bad pixel map for my DSLR as a super calibration frame. I made it around a year ago by integrating approx 8 hours of 5min subs at room temperature. It still works great. and since then I never used dark frames. Only BMP, Flats, and Master Bias.
Recently, I have switched to ASI 1600MM GT (mono) camera. I want to know if making BPM for a cooled mono cam works as it worked for my DSLR. What would be the best way to make it if it works and provides an advantage (along with the dark frames library)? Do i need to use master dark too?
Is the BPM sensor temperature dependent? if yes, then which temperature should I choose? I usually image at -10 degree C sensor temperature. Should I make it at ambient temperature without cooling? and the same for Flat frames (Temperature, filter, etc)Â
I really appreciate any help you can provide.
The BPM is independent of camera settings, including temperature. It's a map of the characteristics of your sensor and the best way to create a good one is to use a few long, uncooled darks. You can indeed just use a BPM, but only if you don't have amp-glow. If you have amp-glow, darks are still vital.
Thanks for the reply. Yes, my camers has amp glow so i would definitely need master dark. But i would make a Good BPM by shooting darks as worst as possible 😅😅 such as ambiannt temperature and high gain.
Thanks again
