[Hans Tucker (Hans)]

The GM8 is out of it's weight class if you are pitting it up against the EQ6 & G11 because the latter two have a similar weight bearing capacity where as the GM8 is half that.

Also I have to strongly disagree with Ron Wodaski's claim that the G11 is a mediocre performer. I owned a G11 and it is an excellent entry level medium sized mount for astrophotography but it is considerably more expensive than the EQ6 pro. I also owned a HEQ5 mount which is the baby brother to the EQ6 and these mounts have come a long way since they first were introduced and as you have already noted many people here on this site have been successful at imaging with the EQ6.

So my recommendation is to go with the best mount which would be best suited to carrying your equipment weight and your budget.

Goodluck with what ever you choose.
