Both focusers were at a slightly differant oriantation to one another.. and on reading your comments above now believe while I was very used to the eyepieces I was getting my eyeplacement just a little wrong ... cheers graham
i have the 8.5 and the 12 they are used on 16 12 10 and 8 reflectors and 8 and 11 sgt. the are better than hyperions stratus and radians they compare with williams uwans 7 and 4 but i think the williams are better due to their wider field of view.However on planets moon,clusters and most messier objects they are very good value.their low weight means that you can also use them on an etx without worring about the gears being stripped and for most scopes you dont need to worry about balance issues.Bintel were very good on service and i cant see the point of buying them overseas when you want a warranty qld
