May 27 2026 APP 2.0.0-beta45 has been released !
Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.
Apr 14 2026: Google Pay, Apple Pay & WeChat Pay added as payment options
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.
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.
I'm using a light pollution filter that I'm told is "broadband" - https://www.baader-planetarium.com/en/baader-neodymium-(moon-and-skyglow)-filter.html . My questions are - is this actually considered a "broadband" filter or a narrow band filter? And which algorithm should I choose when I load my lights into/darks/flats into APP? I'm shooting with an ASI294MCPro OSC camera. The link shows the spectral curve, but I'm including here, as well.Â
Thanks!

Hi Ted,
Â
This is a typical broad band filter, a narrow band (like the name says) let's only thru a narrow portion of light for example a Baadrr Ha 7nm only let's thru the 7nm light from 656 till 663 nm.
Â
You're filter let's thru light from 400 till 700nm.
I would recommend to use the standard Adaptive area disk, this algorithm is the best for these kind of filters.
Â
Hope this helps.
