Bob's Knobs Adjusting Screws for Celestron SCT 11″ f/10 Metric

Bob's Knobs for Celestron 11-inch f/10 SCT Metric: Collimate your Schmidt-Cassegrain without tools

This set replaces the small collimation screws of the secondary mirror on the Celestron 11-inch f/10 SCT Metric. In a Schmidt-Cassegrain, the secondary mirror is in the center of the corrector plate: a screwdriver slipping can directly hit the glass. With thumbscrews, you collimate by feel, safely and extremely finely.

Bob's Knobs replaces the original screws with stainless steel thumb screws with knurled grips. This allows you to collimate entirely by hand: no screwdriver over the optics, no rolling away Allen keys in the dark, and full control even with gloves on.

Features

• Three stainless steel thumb screws with knurled grip
• Aligning without tools, even in the dark or with gloves
• No risk of slipping with a screwdriver over the optics
• Corrosion resistant and mountable without permanent modification

Compatibility

Suitable for the Celestron 11-inch f/10 SCT with metric thread, including many more modern models. Check the manufacturing year and thread type of your telescope: Celestron has used both standard and metric threads over the years.
