Hi folks!
Over in the cloudy nights forum, some members have suggested that I change the original visual back (1 1/4 inch) to a full size 2 inch one from A.P.
Would anyone like to comment on this, or has actually changed to a larger visual back that can advise if this is worth doing?
My largest diameter e.p field stop is a bit over 1 1/4 inch and I wont be doing any photography with huge CCD sizes, so I'm a bit confused at the moment.

Rob.
