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 am trying to do a mosaic that covers 3 different panels and with 1.083 stable it is taking forever. I've never had one take anywhere near this long. I have an 18 core Xeon with hyperthreading and this is using over 90% of the processor causing the processor to be maxed out. I have never seen this happen. Did something get broken in the upgrade? I have a total of 437 subs at 10 minutes each of SHO. Previously this would have taken a fraction of the time to do this. Registration is where the problem seems to be. That is the part that has been stuck for almost 9 hours. It is acting like it is still running, but has been stuck at 80% for over an hour now.
That is odd as APP should be even faster now. Anything you can see on the system that might cause delays or in the console?
Hi @imnewhere,
I suspect that the actual mosaic calculation is not converging normally so it does not stop. That can happen if there is a problem with some of the registrations between 2 images... Usually that is solved by detecting more stars in 3).
First of all, are you loading 437 subs directly into mosaic registration ? If so, please do not do that, because it is a very suboptimal workflow.
First make your mosaic panels, so that would be 3. Then simply make a 3 panel mosaic, that is much more robust, precise and faster 😉
If your problem occurs with only 3 mosaic panels already, then you definitely need to increase star count and possibly scale stop. Did you try that?
I will be very happy to play with your data for testing purposes as well and give you feedback about what exactly is happening and what the best workflow would be 😉
If you want, please upload the complete dataset here:

Make a folder with your name-mosaicIssue and I will test it quickly 😉

To be sure, I just tested a nine panel mosaic over here and everything works as expected, so nothing broke in this sense in APP 1.083. When the progess indicator shows 80% it is doing the actual mosaic calculation for all frames together. And if that takes forever it means can't converge so there must be a problem with 1 or more of the 2-view registrations, meaning registration between 2 images in the data set.
