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.
Hi,
yesterday I started taking subs of M101.
After 60x60sec subs I decided to check the result so far (because m101 was almost unseen on single subs and I wanted to confirm my position).
Calibrated with flats and bias, I got an image with a lot of color dots that seems to run from left to right (the dec orientation of the frame).
Help on this issue is much appreciated.
Thanks
@ofergol Hi Ofer, those colored dots are hot pixels which you can get rid of by using darks as well.
Yep, Darks and dithering!
Thanks.
I added darks and got a strange error message (attached).
What am I doing wrong?Â
I think all parameters are the same.
Log files for light/flat/dark are attached.

0.03 seconds is too short for a flat, you need to get that up to 1-2 seconds preferably. You also need a masterbias or darkflat to correct them with the same exposure length as the flat.
