Bob's Knobs for Celestron Newtonian Telescopes: Simplify Collimation and Locking Wide Telescope Compatibility: Designed for Celestron C6-N/NGT, C8-N/NGT, and C10-N/NGT Newtonian telescopes. Part Information - Part: SWpri: Telescope Fit: Perfectly matches Celestron C6-N/NGT, C8-N/NGT, and C10-N/NGT models. Primary Collimation Knobs: Crafted from black plastic, 16 mm (5/8”) in diameter for easy grip and precise collimation. Durable Threads: Features stainless steel threads for both collimation and locking knobs, ensuring lasting performance. Primary Lock Knobs: Distinctive red plastic knobs, 16 mm (5/8”) in diameter, for easy identification and adjustment. Enhanced Telescope Functionality: Dobsonian Compatibility: Ensures the optical tube assembly clears the Dobsonian rocker box with the primary knobs installed. Simple Replacement: Knobs with shorter screws and spacers are designed to replace factory flathead Phillips collimation screws. Longer screws replace factory set-style (grub) locking screws. Staggered Knob Design: Due to the proximity of factory screws, knobs are staggered in height for accessibility, with locking knobs protruding further and colored red. Installation Note: Removal of the cover over primary collimation screws is necessary when installing Bob’s Knobs. Care Instructions: Protect the red locking knobs from damage and avoid using them as support feet for the OTA. Easy Adjustment Solution: Ideal for astronomers seeking a hassle-free way to maintain and adjust their Celestron Newtonian telescopes.
