I use CCD Navigator to select targets and set goals. It also frames the images so I have a suitable guidestar. That integrates nicely with CCDAP so I can prepare an imaging run over several targets for a series of nights. I then let CCDAP start itself, frame and commence imaging. Without a rotator I'd be fiddling with framing every night - and not getting the real benefit of automation.

I've not used a flattener so I can't comment on that.

My 2 cents worth

The STX would have that problem for sure and I see why you need the rotator for that very reason. I never quite understood the reason for guiding through filters. That is a pain.

You don't need a flattener for obvious reasons with the CDK. Nice flat field to start with. Starting to think it might be easier to have gone down the CDK route myself.
