I have for sale (1) T/V "Starbeam" reflex 'red dot' finder in mint condition. I had this mounted on the Celestron C102 Fluorite refractor I sold here on the Astromart last week. I no longer have a need for it, so if you're looking for a high quality precision machined metal reflex finder vs. some cheap plastic reflex finder, this is it. I just couldn't see having a $40 finder on a $2,000+ telescope with another $2,000 worth of high-end eyepieces, diagonals and such in my accessory box. The adjustable intensity red dot, I found easier to use than the circles of the 'plastic' finder. These currently sell for over $200. I offer this mint speciman at $125. Email me should you have any questions. Good seeing...Mike P
Added...Original flat bottom type, no 90 degree R/A attachment.
