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 have learned to try to carefully read the help scripts in APP because there is a lot of info there. But I realize I still lack expertise.
My question is, is there anything to be gained by using the individual frames from each session, versus "stacking the stack" of a previous session with a current session?
If I just stick the previous, completed, unstretched stack as a "light", is that as good as re-entering the raw data from a previous session from scratch?

It's a very good question and it basically goes like this:
- If you have enough frames for each session that you can get rid of outliers, then you can stack multiple sessions and then simply combine the sessions as a final stack
- If you dont have a lot of frames per session, then it's better to integrate everything together so that outliers get averaged / medianed out
- If you stack the stacks, you can manually get rid of light pollution on each individual stack before stacking them (alternatively you can use Local Normalisation)
- If you use Local Normalisation Correction you're likely going to get better results keeping all of the images (but it's going to take ages)
More concretely: If you have more than 30-40 images per session then stack the stacks and you'll be fine
Hope this helps!
