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.

New to APP and trying it out.  I shoot with a nikon D5300. If I comprehend correctly, APP expect flats with 
the same exposure time as bias. I always thought that bias was suppose To be the fastest exposure possible
and then flats were to get ADU at about 50%. I use the t shirt and tablet for lighting. I suppose I could
slow the bias as that may be easier than trying to get the light to correct intensity which right now I am
already maxed out on the intensity side. Not sure if slowing bias downis smart although we are talking the
difference of 10 milliseconds to 120 ms which my flats currently are at.

Do you have any input?

It is a LONG thread, but maybe read this first?

APP doesn’t require flats with the same exposure time as Bias. That would be rather odd as flats are usually taken around 0.5-1 seconds of exposure time. Dark flats you might mean, those are at the same time as flats.
