One more thing , you may have to buy a Vixen dovetail to bolt to the rings allowing you to fit the scope to the EQ5 ( thats the mount I would grab ) because from memory the EQ2 mount ' Hard bolts ' to the tube rings .
Look at Andrews , Bintel or others for the Vixen dovetail , get one 200mm long and you are away
, small outlay in $'s but you need one .
One more thing , stick with the 130mm scope as these really do perform well , these deserve the EQ5 class mount .
