Thanks, CC. Yes, I'll bring it to the JuMP on the 5th. Anyone in the east can give me a lift?

Btw, if anyone thinking about making 10" f/6.4 for EQ-mounting, think again.
The height of a 10" f/6.4 (or 12.5" f/5.3 or 14.5" f/4.6) will be similar to this picture ...

Nice!!! BTW, Arief, why is it that in one picture (the one with your son) the scope looks shorter than the last picture? My eyes are playing tricks on me!
