Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and it will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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 took Darks, Flats, DarkFlats and Bias frames yesterday, and loaded them up and ran calibration against them, following the workflow in the videos here. Â Darks, DarkFlat and Bias all resulted in Masters that looked as one would expect, a smoothed version of the subs.Â
However, the Master Flat was basically black, even with various stretching in APP or other viewers. Â I redid all the flat subs again tonight, very carefully (wizard in Nina). Â They all look as one would expect, dull grey with some vignetting at the corners. Â Calibrated in APP, and the result is all black again! Â Hovering over the image in the viewer, appears RGB values are all 01638.
Any ideas?? Thanks!

From the screenshot I can see you took the flats at 0.15 seconds, at least that is something you want to bring up to 1-2 seconds. How does a single flat look like and what are your gain and offset values?
I did find my problem, I accidentally created my DarkFlats with the same pictures... hence when calibrated they normalized to nothing!
Excellent, that is good to know! 🙂
