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.
Hello,
I am considering testing the Radian Telescopes Triad Ultra Quad-Band Narrowband Filter on my DSLR
Will it be possible to extract the 4 channels, Hydrogen-beta, Oxygen III, Hydrogen-alpha and Sulfur II separately? In order to then create an image in Hubble Palette, for example.

With a DSLR you can't separate all those bands with a quad band filter, APP can extract Ha and OIII from the data and HB and SII will then be in the mix of those signals. If you search the forum for "quad band filter" you can find a lot of discussions about this specifically. You can have filters for SII alone etc and then you can play around with that data (given your DSLR is modified as otherwise a lot of signal will be filtered out by the filters already on the DSLR sensor).
- Ok thanks. My camera is modified... so could I then extract Ha and OIII from a shot with a dual band filter (e.g. Optolong Extreme) and take a second shot with an SII filter and then combine that together?
