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.

Thought this might be of interest to some. 

East Midlands, UK, 22nd October.

63 (of 71) x 60s, ISO 1600, Canon 5D Mk IV + Canon EF 100-400mm MkII at F5.6

30 Flats, 25 Bias & 23 darks.

No filters

M33 ISO 1600 small

 

Obvs more integration needed; weather has been rubbish... but maybe I'll hold off on buying a decent refractor for now after my woes with the SW ED80?????

 

Kind regards

Stephen.

Could you remind me briefly what your woes were about? Usually a refractor is quite nice in the sense of not needing a lot of correction.

Hi Vincent, 

The ED80 "woes" were the the rainbow artifacts from using flats, amplified by field flattener use as discussed here:-

So far so good usung the Canon lens. It is a very sharp lens despite being a zoom.

Regards,

Stephen.
