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.

Just pulled in this data from last night, stacked in APP and removed light pollution, calibrated stars. Looked so good, I just popped it into Topaz Denoise to clear it up, tweaked the saturation in macOS Photos, and it looks darn good! I might do some other  magic on it, but really not sure what I'd be trying to improve!

Just shot it last night, so no moon until early morning. Not sure what see was, probably < 2.5”.  Was lucky to have clear skies all night, only had to toss a couple frames due to bright satellites. 7.5 hours total time.
