Bob's Knobs for Meade 10" f/10 with 3-Screw Secondary # M10-3

Description Ordering Info USA Shipping International Orders Returns Our eBay Store


Collimate your Catadioptric or Newtonian reflector style telescopes without tools!

It's easy...just grab a Bob's Knob collimation thumbscrew and turn. You can even do it while looking through the eyepiece on most scopes. These thumbscrews are also much easier to use with gloves on. And perhaps most importantly, you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

Part: M10-3
Fits: Meade 10" (25 cm) f/10 SCT versions with three screws on the secondary housing (2120, LX10, LX50, LX90, LX100, LX200, others)

Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Black anodized aluminum alloy


1. The factory dust cover will fit normally with Bob's Knobs installed.

2. Some post-2004 Meade 10" telescopes have six screws on the secondary housing. The 6-screw secondary requires different knobs (see Item M10-6) Do not use knobs for the 3-screw secondary on the 6-screw secondary. The screws on 3-screw knobs are too short.

3. An Allen wrench for removing the factory collimation screws is included with your order.


Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.
