Oh, by the way...

My 6" f/10 has a 54" tube. The cell is mounted recessed in the sky end, and I have a University Optics 2" focuser on the other end. That thing is almost identical to a Meade 680, so it's about 4" high by itself, and with another 3.5" added (needed) for a 2" diagonal, I'm right up around 61.5" from the center of the lens.

I'll still give it a check tonight, though.
