Bob's Knobs Adjusting Screws for Meade LightBridge and GSO Dobson Secondary Mirror

Bob’s Knobs for Meade LightBridge and GSO Dobson: tool-free collimation on your Dobson

This set replaces the Allen screws of the secondary mirror on Meade LightBridge and GSO Dobsons. It is best to collimate a Dobson before every observing session; with thumb screws, that is done in a minute, without an Allen wrench and without risk over the open tube.

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 secondary mirror cell of Meade LightBridge and GSO Dobsons. Replaces the original Allen screws one-to-one.
