Flat frames coming ...

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.

Hi, 

 

Not sure if this is specific to Mac but I've just downloaded the latest version of APP and my flat frames are coming out green. I check on previous sessions flat files at they are also turning up green. I'm quite new to the software so feel I may have missed something?

 

Thanks,

Vincent

Most likely due to the RGGB matrix of the sensor and the two green pixels dominating, as seen in the histogram too. I can't recall if mine look like that but a green cast is quite normal I'd say.

@wenxin As explained by Martin this indeed is perfectly normal. APP by default debayers the raw images which is why they show up in color.
