I just got a 300mm F/2.8 lens on monday, And I've been at a bit of a loss as to how to mount it to my EQ6 Pro for some astro-snaps. With my 70-200 I just used the piggyback adapter on the top of the rings of my 6" refractor, however, due to the enormous weight in the 300mm, if i do that, when the mount rotates on the RA axis, the camera instantly just spins on its tripod colar and points straight towards the ground...

I was thinking of making an adapter out of some aluminum that would support around the sides of the colar that would prohibit rotation.. but thought I'd ask what other people do before I jump in the deep end...

Cheers.
