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.
How do you tell APP to apply bias correction to your flats and/or flat darks only?
Wayne
Hi Wayne @whixson,
APP will apply bias and/or dark flat Masters to your flats if they are available. If they are not, APP will give you a warning that you will not be able to get good flat-field correction without bias and/or dark flats available.
So APP will automatically do this correctly, you will only need to supply the bias and/or dark flats and they will be used 😉
Kind regards,
Mabula
Thanks Mabula, what if I don’t want to apply bias to the lights but only the flats?
Hi @whixson, then you will first need to create the masterflat with the bias loaded.
Then remove the bias and masterbias and load the lights...
But... why would you want to do this ? The light need to be calibrated with either bias or darks.... otherwise flat-field calibration will not work.
What would be an argument to not use bias for lights?
