June 24 2026 APP 2.0.0-beta46 has been released !

Improved internal memory configuration (lower ! memory usage), fixed beta45 startup issue, fixed Set Save Directory & 2-panel mosaics.

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.

Hi, been using APP for a few years now and this is the first time my flats arent calibrating my lights. I searched and tried all the tips I found in the forum, any help would be appreciated.

@pcapino Hi Paul,

What indicates that the flats aren't working? Can you explain as much as you can about the optical train, camera, type of data and flats so we can try to help you solve this?

@Wouter, I'm using an ASI294mm with a 2" EFW + .8 reducer + skyrover 72ED. For acquisition I use ASIAIR, but use the flatwizard of NINA. 🙂  This is a stacked 1.5hr image of HA (no darks here). Gain 120/Offset 16/ Bin 2.

and here is the flat. I tried a tip of exposing at least 2 sec for the flat.

@pcapino Hi Paul,

Combining calibration data taken with multiple software doesn't work well. Any chance to take the flats with ASIAir as well? It has a flat wizard as well.
