Hi Dob, oops! I mean Hi Phil.
I own a 12" dob and it's o.k. I suppose (chuckle).
I would like to put my house in hock and get a megasaurus Meade but my dog likes eating the sheep, so I can't sell up and move.
I have not gotten into photoastrography shooting yet so I have no idea about anything other than bloody big Dobbers.
They are easy to move around the sky, reasonably easy to move from inside to outside and back again (very easy and quick to move inside when the fog rushes in) and they look damn impressive when the neighbours call in: "Good grief, look at the size of that thing" (the scope).
Seriously, a Dobber is very easy to use.
Can't speak about Go-to's and tracking scopes coz they got computer thingies and motor bits and that stuff scares me.
Hope I've helped
