This is an Orion SCT thread-on 2" diagonal. I don't own an SCT, so this is of no use to me. Excellent condition, has both end caps, but does not have a 1-1/4" adapter. Item is used, but I'm not the original owner.
Retails for $79 + shipping, mine is $50 shipped anywhere in the US. Paypal prefered, money orders ok if necessary.
