Hi peter and David , I have the Vixen Super Polaris mount and its a very nice mount with vixen duel axis drives that are super smooth and zero backlash , non GOTO .
I have an IEQ45 for that .
The easiest way to tell a SP from a GP is the SP has 4 allen head bolts holding the Declination axis of the mount onto the RA axis , in a square shape about 90mm square , the GP mounts are like the EQ5 Synta's and they only have 2 .
You can see 2 of the 4 bolts here on mine under my SKY90 .
Oh yes the Super Polaris does not have a vixen dove tail only a plate with 2 captive knobs for attaching your OTA , not like the Great polaris that has one ( and EQ5 Synta copy )
