Hi there! I have an excellent ETX 90 ota for sale. Comes with the stock finder and all caps. This scope is in excellent condition (basically like new) and gives very nice views. Collimation is much better on this one than on many that I have seen. - $135 shipped to Canada or ConUS.
I also have the Large accessory ring for this that I'll include for an extra $20; lets you use regular SCT accessories (i.e. visual backs, 2" diagonals, t-adapters) with the scope.
