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,
I am in the process of making a Good Bad Pixel map using 100 dark frames of 5 min subs at an ambient temperature of 25 degrees C for my Nikon D5300a. As it also needs flat frames so I am a bit confused. Do I need to separately use flat frames for the broad and narrow bands? Or there is no relation between Bad Pixel Map creation and flat frame bandpass (broad band or narrow band)? Mostly, I use either a UV-IR cut filter or a dual narrow band filter. First I will make Bad Pixel Map using Broad Band Flats.
Please let me know.
Thanks
Not really necessary to use different filters, just use a broadband flat. And you can create one from just a few dark frames, best is to make them as bad as possible (in the sense of a warm sensor and long exposures). A BPM is not going to hurt your data, it just corrects what it could detect if there.
