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.

 

missing metadata in master frames?

I may just not have found it, but I cannot see the focal length in a master flat - either in the FITS metadata or as part of the filename.

My input files have focal length set - exiftool shows it as:

Focallen : 390

but I cannot see it in the master file, which makes it difficult to keep track of the various combinations of telescope / lens and barlow / extender that I use.

Is it lurking somewhere else, or should this be a feature request?

@pootle The master files produced by APP indeed don't contain many of the metadata and this is on the TODO list to be improved.
