  1. Having an EVO 9.25 I am thinking of one classic upgrade path, a 2" diagonal, which would also help to share eyepieces with the planned buy of a big dob. I have read plenty of existing discussions, but am still lacking enough information on the right one to choose. In particular, the missing point is about clearance and combinations: I have read a short diagonal that fits directly in the SCT thread (like WO) should allow for clearance (pushing up the OTA), therefore allowing the scope to work at its full potential. My doubts are: 1) does getting rid of the visual back cause big problems? I have read it makes hard to block the diagonal at the right position, and that it can make the diagonal dangerously swivel 2) if there are indeed problems, and keeping a visual back (like 2" Baader's click-lock, for instance) is better, wouldn't this prevent clearance? 3) I am tempted by the 2" baader click-lock dieletric for its no screws capablity: is there a combination that allows clearance for this diagonal? Anybody help please? Thanks! Ab
