Atlas is mounted in an observatory on a 1" thick slab of aluminum and very solid.
Here's what I am thinking of trying.
C8 - 11.25lbs
AT111 - 15lbs
WO 80mm guide scope - 6.2lbs
Side by side mount - 6lbs. + dove tails and rings, guide camera and Canon 20Da.
I guessing between 40 - 45lbs total weight. What do you guys think, am I asking too much from the Atlas???
