many thanks
I have an EQ-6 with 10" f4.7 newt (The Synta Version). I also have the ED-80. The mount will carry the combination IF you do some modification. The 10 inch is held onto the mount by a small dovetail that is similar in profile to a vixen or eq-5 dovetail. This is a weak point as the dovetail twists and the scope flops around. You need to replace the top dovetail mount on the eq-6 with a new one fitted with a losmandy or similar mounting rail. There are several threads on cloudynights.com relating to this. The mount itself can carry the weight (about 18kg for the newt + ed80 + rings etc), but the standard dovetail cannot. You will also need at least 4 standard counterweights to balance the scope if you mount the ed80 on top of the newt. If you cannot do this then forget about the combination, it just doesn't work (and I've tried it) You should try side to side mounting to if possible. Add a camera and you are at the limits for imaging. I personally would prefer an 8" f4 and would use 2" barlows to increase focal length. I'm actually considering selling my 10" to do just that!

Hope this helps. FWIW

cheers
Gary
