Bob's Knobs Adjusting Screws for Celestron SCT 8″ (post-1980 Standard) make collimating your Schmidt-Cassegrain telescope easier and safer than ever. This set replaces the original, small secondary mirror screws with three stainless steel thumb screws with knurled grip. This allows you to perform collimation completely by hand, without risk of scratching or damaging the corrector plate.
The advantage of Bob's Knobs is instant control over the alignment of your optics. You can make even a small adjustment accurately, resulting in sharper images and a perfectly centered optical axis. Collimation is crucial for maximum contrast and detail in observations of the moon, planets and deep-sky objects.
Bob's Knobs is the world leader in manual collimation upgrades and is known for its high finish quality. The screws are durable, corrosion resistant and designed specifically for Celestron SCT models from 1980 onward.
Application
Ideal for owners of Celestron SCT 8″ telescopes who regularly check their alignment or often observe on the go. The thumbscrews allow quick adjustment in the field without tools - a must for those who want to maintain maximum sharpness under changing conditions.
