Bob's Knobs for Sky-Watcher Newtonian Telescopes: Precision Collimation Made Easy Unlock Collimation Precision: Elevate your Sky-Watcher Newtonian telescope's performance with Bob's Knobs. We offer a range of knobs designed for primary and secondary collimation, tailored to Dobsonian mount configurations. Part Details - Part: SWpri: Primary Collimation: Achieve precise primary collimation with black plastic knobs featuring a 16 mm (5/8”) diameter and stainless steel threads. Ensure your telescope delivers impeccable visuals. Primary Lock: Enhance your collimation experience with red plastic knobs of the same dimensions and stainless steel threads. These knobs provide secure locking, preventing unintended adjustments. Compatibility: These knobs are exclusively for Sky-Watcher Newtonian telescopes equipped with factory collimation screws. They are not suitable for telescopes with factory collimation knobs (see Item B below). Complete Set: Our listed price includes a comprehensive set of knobs, allowing you to optimize your telescope's collimation with ease. Note: Ensure your telescope has factory collimation screws before selecting these knobs. They replace the factory flathead Phillips collimation screws and set-style (grub) locking screws. Keep in mind that the locking knobs protrude further than the collimation knobs and are distinguished by their red color. Usage Caution: Avoid using the locking knobs as feet to support the optical tube assembly (OTA) to prevent damage. Upgrade your Sky-Watcher Newtonian telescope's collimation capabilities with Bob's Knobs for unparalleled precision and ease of use.
