Thanks, folks - so dob it should be then.

Is the OTA of, say, an 8" dob mountable on an equatorial or motor driven mount, should I decide to go down that path later on?

I read somewhere that motor driven alt-az mounts have in many cases eliminated the need for equatorial mounts, if all you want is steady tracking for long exposures. As I understand it an equatorial mount means you just have to move one setting for tracking, whereas with an alt-az mount you need to move two.

And as possibly a very foolish beginners question, say I was looking at Saturn with the highest usable magnification on an 8" dob - how long would it remain in the field of view, and how easy is it to hand track such an object for visual observing?

Thanks again!
