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.
Was following the tutorial for mosaics but got this during register
Encountered error in module:
MultipleViewDistortionAndCalibrationTask
Error message:
java.lang.ArrayIndexOutOfBoundsException: 10
Cause:

1.083-beta4 on Linux Mint 20.2
The crash was with scale start at 5 and stop at 12 as per the tutorial but changing these to 1 and 15 made the crash go away.
I eventually managed to get the mosaic to work but only by changing some recommended settings and increasing the stars target to 1000. Made the CPU roar for quite a while even though there were only 29 subs.
The results was less than brilliant, loads of weird artefacts and not much like the individual stacks I made externally so I think I will stick with butt joining my mosaics in Gimp.
It was good to test though, thanks for letting me have a go.
I think you haven't switched on MBB and LNC, that will blend the panels nicely and very accurately. It's one of the best features APP has. 🙂 So I'd advice to give it another shot.
Hi Franco @altaloma,
Indeed, like Vincent indicates, you need to enable MBB and LNC in 6) to get a nicely blended and seamless mosaic 😉 !

Thanks, I'll try again tomorrow.
I tried the settings you suggested but with the 4 prestacked panes as input and got something that looks much better than my first effort. I'm sure with a bit of experimentation it could be a lot better still.
The 2 lower panes were after a flip and the tracking wasn't great so only got a few good mages, plus I think I caught some moon beams.
This looks like a great piece of software but way too advanced for me at this stage, I've only recently started astrophotography - as you no doubt can tell!
Cheers,
