This is an f4.5, 13.1" Coulter with a Pyrex mirror which has been remirrored in the last year. The scope has been overhauled and is slick and comes complete with a 7x50 finder mounted on large rings to accomodate a larger finder.
Mirror is sling mounted and easily removed for transporting. Collimation is simple with 3 screws on back of cell. Cell is 9 point contact.
Secondary is well placed and easily adjusted while at the eyepiece.
The Dob Driver II comes complete with instructions, two batteries and a battery charger. This unit automatically picks the slew speed depending on whether you are viewing deep sky objects, the moon, planets, Sun, or wandering space bodies(asteroids, comets, satellites). Easy to use and can be coupled with Digital Setting Circles. I had a Sky Commander in use with it. Very nice.
Scope has a 1 1/4" all metal Rack and Pinion focuser.
Include a 1/4" plywood Heculean off axis mask.
