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 took five 300 second narrow band images of the Iris Nebula with iTelescope T24 in each of Ha, OIII and SII. Registration is failing in APP. I think it's because most of the stars are too faint. Attached is the jpg version of one of the images. The stars are faint but visible. Can anyone suggest how to adjust APP to register these images? I tried reducing the number of stars in analyze from 500 to 100 but this did not help.
Most of the time, if stars are actually ok enough (even more faint ones), it should be able to find them. Did you download the corrected images or the raw ones? I've noticed that sometimes the corrected images are faulty due to issues in calibration. Also, the light you show here doesn't look very good to begin with, with 300s I would expect a bit better signal, for narrowband though I tend to go to 600 or even 900 seconds.
