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.

Hello. I used Orion image stack with STC duo narrowband filter to try separate Ha and OIII channels and recombine them. Fuji X-T3, fujinon 55-200 at 200mm, STC duo Narrowband filter, 60x60 seconds, iso 800, Flat, Dark and bias frames. I am quite pleased with the result considering the type of mount I use. APP is an amazing tool.
