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.

This mosaic started in 2021 when I noticed that five of my images in the Cygnus region have overlap. From here I started growing this image.

After two years I had to build a dedicated computer for this task (my Mac only has 64 GB RAM), so I bought some used server-stuff and lots of RAM (768 GB) and 12 TB NVME-storage. I did not go wild with the CPUs, computing-time was not a big deal for me, so two elderly 8-core XEONs did the job (although the last and biggest image took three days to compute). 

It now contains 190 sessions and 640 hours of exposure-time.
This year had not many clear nights, this is why I built a second identical rig for producing more mosaic-tiles.

Now my server is starting to loose more memory on every start, I think it is reaching it's end of life. So this project for now is frozen and I would like to present a big part of it to you. 

You can visit a zoomable image on my homepage.

There you also can see the whole unprocessed and uncropped mosaic.

It would have been a good thing to get some bugfixes and further development in APP, sadly nothing happening any more as it seems.

Wow Walter, that is really awesome!! Congratulations with the result and your dedicated work.

I will continue APP's work for sure, sorry to have kept you waiting.
