First, I would like to state I have no idea how much this is worth. I know Clave' has an excellent reputation(one of the best) and is to my understanding no longer available. This barlow is 2x I think. It compares very closely to my Celestron Ultima. It is in excellent condition. It looks like it was hardly ever used. As stated I do not know what this is worth so I am asking $175 shipped to US. If this is way too high please tell me so. Paypal prefered but Mo okay too.
