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,

please forgive me, if this topic has been addressed bevore. I am just curious, why not intergrate "the normal way" and do the mosaic afterwards with the integrated frames? I've done some test with a 4-panel mosaic from cirrus complex using the mosaic registration with over 200 subs. It took over 4 hours to do the mosaic. Whereas it took half an hour to do the mosaic with the already integrated panels. I have just loaded the panels as lights, switched on mosaic-registration and did an integration. Well, I know, there is no real data to stack this way, but it seems to work.

So, I guess, its more precise to do the reg with all the subframes and stack together the whole mosaic, am I wrong?

CS,

Chris

I think you’re actually explaining what indeed is the best way to create a mosaic. 😉 Just creating a mosaic with all subs is not the way to go, the analysis on those becomes very complex and takes a long time. The best way is, like you figured out, to first create the panels separately and then creating a mosaic with those. I would still advice to have at least 20-30 subs per panel though, so the rejection algorithms work the best.

One thing I would say is:

if you have very large overlap between panels, doing the integration with individual frames will still improve the blending (if you enable blending and with a relatively large blending %). But being able to remove light pollution from the individual panels prior to composing the mosaic is also a big advantage. So your mileage might vary...
