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.

I feels all Ha and hardly any OIII

I used the method where two FITS are created, one with extract Ha, second with Extract OIII and then they are merged. Is this what its supposed to look like, or I'm doing something wrong. I will share both the FITS

I used all default settings
