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 have been using several dual narrowband OSC filters successfully with APP for some time, but  am surprised that several FITS header fields are missing from the extract HA or Extract OIII stacks when these algorithms are used. In a normal OSC stacked integration I see that the RA, DEC, and pixel size information are included, but these header fields seem to be missing when I execute either the HA-OIII Extract HA or HA-OIII Extract OIII algorithms, as well as several other FITS fields. Is there an option to preserve these other header fields  when one of the Extract HA or Extract OIII algorithms are used? Thanks.
Hi Jim @casejim,
Thank you very much for reporting this. I will have a good look at the FITS headers of these dual NB stacks. I also have on my list to include all the important headers for astronometry. SO I will try to fix it soon.

All of the headers would be a real valuable addition. Thanks for your efforts to include these. Jim
You are most welcome Jim @casejim,
Thank you very much for mentioning this shortcoming. I will try to have it fixed in the next release version 2.0.0-beta33.
Mabula
Thanks for your work on this Mabula. I will download the new release and appreciate the new functionality. Jim
