Hi Mike, Thanks very much for all the really useful info & replies in this thread, very interesting and informative. I've been looking for some time for a suitable alt-az mount for a S/W 150p-ds (if such a thing exists). Do you think a 6" newt would be too big for a mount like this? (assuming of course i have it on a suitable tripod). I cant quite decide if it would even fit, especially when pointing higher up, its hard to tell how much clearance there is between where the dovetail attaches, and the base of the head. Any thoughts greatly welcome
