Greetings, I am trying to find a practical way to quick release mount a Telrad on a Televue Clamshell ring. I do not mind modifying the $40 Telrad but I just do not want to put sticky tape on my beautiful telescope. Plus, the size of the Telrad would inhibit proper balancing of the scope. I've spoken to lots of people about this and haven't had much luck. I would love your suggestions! Thank you, Jeff

You can buy Vixen/Orion/Celestron finder dovetail that fits the TeleVue clamshell, not sure where but my NP-101 has one.
Then you can buy a Telrad to Vixen dovetail mount. Not sure where, maybe Scopestuff.

Mount a TeleVue Quick-Release Bracket (QRB-1002) to the clamshell. Mount a QRD-1006 dovetail to the base of the Telrad by drilling two holes to align with the tapped holes of the dovetail at the desired position. You might want to fabricate a base plate or a simple spacer out of suitable material (wood, plastic, aluminum, etc.) to fit between the dovetail and the telrad base to provide strength as well as to accommodate the required height above the clam-shell and the QRB or buy a couple nylon standoffs. You will need to buy two button-head screws of the correct length/thread pitch to secure the three parts together.
