Hi Mike,
I have an Atlas same as EQ6. In all honestly don't bother with this mount for your 10". Please don't waste your money.
The EQ 6 is ok for little scopes like mine or an 8" sct or 9.25"sct. But thats about it. People will say different, but that's there opinion, this is mine after using one.
Save your money and get at least a G11 or bigger.
