so there is a piece of glass in the focuser? Your focuser shoudl have nothing in it.. i.e you should be able to stick your finger through the focuser and touch the secondary sort of thing.. but don't touch the secondary.
I really don't know how it all works.. but i woulda thought u coulda used the existing mirrors in a proper 1400mm tube.. and end up with a decent(as long as the mirrors were ok) f9 reflector.
But yeah.. if u can get a refund, get it. Then.. GO FOR A DOB! cause then u can be part of the dob brigade™.
