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.

For a long time flats have plagued me. I have been using APP with only the remove light pollution tool and get VERY good results. This week I decided I was going to get my flats working. Well I have failed so far. My flats are over correcting. In the three images you will see my linear and calibrated lights, and my unstretched flat. The unstreached flat looks like it should work and the result has the data in the correct place, it is just too much. 

linear
calibrated
Masterflat

Here is a link to the source files, 5 lights, 5 darks, 5 flats, and 5 dark flats.

Any way I can get someone to take a look and see what I am doing wrong?

Thanks
