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.

Tried to fix vignetting but not sure what happened, bottom pic is a 30 second sub the the next pic is a stack of 60 with darks and bias, did not have flats. The first pic is after correction.

So that is sometimes tricky indeed. What I did in the past (when I didn't have flats yet), was to first calibrate all my lights with darks and bias (bias being 0.02 seconds at the minimum) and save those lights (tab 2, first calibrate, then go down and select to save them). Then I would load 1 of those calibrated lights and use that to make an artifical flat. Then I load in the calibrated lights again and use that flat to correct.

I think the important step was to calibrate the lights first with darks or bias. Of course the best is always a real flat.
