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 am processing a RGB combined image using an extracted Ha and OIII channel to to simulate a HOO color image. My question is, would it be better to do the light pollution removal on each channel before I combine them into an image or combine the channels first then do light pollution removal?

@darin0101 Hi!

That is a good question and unfortunately the answer is "it depends". If there is a big difference in light pollution between Ha and OIII then it may be better to reduce it on the individual panels. If it is more or less the same then you can do it on the combined result. But you will need to try and see what works best for you.
