This came with my NexStar 11 GPS, but I have gone to 2", so this one is for sale. It is brand new in the box, never even used. These are $39.00 new, so I'll let this one go for $25 and I'll pick up shipping in the CONUS.
Interestingly enough, this one has an endcap with TeleVue on it. Makes me wonder who made it.
I'm also selling the 1.25" visual back if you need both.
