Bob's Knobs Adjustment Screws for Celestron SCT 11\u2033 f\/10 Metric are designed for demanding observers who want maximum control over the optical alignment of their telescope. This replacement kit replaces the original small secondary mirror collimation screws with three solid stainless steel thumb screws with knurled grip, allowing you to collimate without tools.<\/p>\n\n\n\n

Thanks to the precise thread and sturdy construction, you can make extremely subtle adjustments to the mirror. This visibly improves image quality: stars stay sharply focused, details on planets are more visible, and deep-sky objects show more contrast. The sturdy fit prevents the alignment from shifting quickly, even during transport or temperature changes.<\/p>\n\n\n\n

Bob's Knobs is known worldwide for its perfect balance of ergonomics and precision. This 11\u2033 f\/10 Metric set is compatible with Celestron telescopes with metric collimation threads, including many modern Schmidt-Cassegrain models.<\/p>\n\n\n\n

Observation goals<\/strong>
Ideal for owners of Celestron SCT 11\u2033 telescopes who regularly collimate or take the telescope to observing locations. The thumbscrews allow fast, accurate and safe adjustment without risk of scratching or losing small parts. Perfect for astrophotographers and serious observers who demand maximum sharpness.<\/p>\n\n\n\n
