Ok, so with a thread like this I have to show my "premium" 13 inch dob.
I don't have any comparable scopes to be able to address technical comparisions.
Any way, this is a one of a kind built by Mel Bartels (so sorry it is not available to all).
Scope Folds for transportation - that gives it its name "the zip dob"
Total Weight is 31 pounds for the OTA - about 10 pounds for the table/base easy to transport and move.
Less than half the weight of a 12 inch Orion Truss tube (84 pounds) !
Slumped meniscus mirror - saves a ton of weight - 13.2 inch mirror.
F3 gives wide field of view capability and enables the compact size
Mirror figured / finished to perfection. .
Can view objects at zenith while seated.
A true gem of a scope -
