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.

Start by performing a calibration on the lights using a masterdark or masterbias. Press "create masters and assign to lights", after calibration save those lights (button all the way down in tab 2). Then clearing all data, load the calibrated lights again and take one to go through the "correct vignetting" tool in tab 9, in which you get to create boxes in the areas where there is the gradient. You can then check if that works. Check the "create artificial flat" and save that file. Then you should be able to assign the masterflat to the lights (check by switching to "l-calibrated" on top of the APP window).

Make sure your lights are not yet calibrated with a real flat. If that is the case, this tool won't work properly.
Of course, an artificial light will only correct for vignetting, not dust.

After this would we still also use Darks, Bias, Dark Flats ?

or would we just use Lights and the Master Flat ?

 

Thanks
