Knobs for Telrad Finder

These stainless steel knobs replace the small plastic aiming knobs on the Telrad reflex finder.

Installation instructions:

• Tighten the three factory knobs by hand until they become slightly harder to turn. Do not force them.
• Remove one Telrad knob and replace it with a Bob’s Knob. Repeat for the other two factory knobs, one at a time.
• Loosen the new knobs two or three turns.
• Mount the finder on your telescope and align.

The manufacturer Bob's Knobs supplies various collimation screws for Schmidt-Cassegrain, Ritchey-Chrétien and Newton telescopes.

The selection includes screws for primary and secondary mirrors for optics between 5" and 16". In addition, Bob's Knobs offers mounting screws for various mounts from Celestron (CGE, CGE Pro, NexStar), Losmandy (GM-8, G-11) and TeleVue (Gibraltar).
