Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
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.
Most recent project involved about 2.5 hours of L on M51 and a little over an hour each of RGB. The resulting combined stack turned out very noisy and under-saturated. Increasing saturation in APP only highlighted the noise.
As far as I know I've used all of the default settings from calibration through integration. Attached file is linear, cropped and light pollution removal applied.
Suggestions appreciated as always!

Can you show a screenshot? I can only see an unstretched tiff I think
@vincent-mod Apologies for not seeing this response. I've attached a screenshot showing the cropped LRGB combine. Yes I can increase saturation from the tool to the right but that just comes out extremely grainy.

To be honest, that looks totally normal. 🙂 If you stretch more to reveal all the signal around the galaxy, there will always be noise going up as well. It will get better with more data for sure, but not completely gone.
