Extremely nice telescope!
Pros:Strong Construction,Easy to Use,Accurate,Quality Lenses
Cons: Comments:The optics of the 5 element GTF102 exhibit no discernable color, in or out of focus, even when viewing bright stars such as Vega. The built-in flattener easily covers my APS sized CCD camera with perfect stars. The focuser is smooth and stout, with all the adjustments necessary to keep it that way (mine had loosened somewhat in transit). The tube is well made and heavy for its size. Visually it is on par with a friend's very high-end 4" APO. Can't say enough about the quality of this scope. An amazing deal at this price.
