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.

 

Using Flats without Flat Darks or Bias frames?

Some CMOS camera companies claim noise levels so low that dark/bias calibration is often not necessary. Flats are still important I assume. Is it possible to create master flats without dark/bias calibration?

thanks

Wayne

@whixson Hi Wayne, darks are useful for eliminating hot pixels from loghts and flats so you still should take them and use them.

@whixson APP will complain if you do and the lights will not be corrected with the flats.
