I wonder what they put in those scopes to make them so heavy? Is the construction lightweight, or does it just not matter on the big mount?
Btw, is that with or without counterweights...? If you have another 45kgs of metal sitting at the other end of the shaft then the inertia must be quite a bit when making fast guiding corrections. What guiding frequency to you plan to use?

Just for comparison, although mine is a bit smaller at 12.5" it's weighing in at 16kgs which rides very smoothly on the Losmandy G-11 I figure a 14" version would push it to maybe 18kgs.

Hope to see your first deep image soon Marcus
