1. PRODUCT DESCRIPTION
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.
Fits: Vixen VMC200L or VMC260L secondary
Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Stainless steel
1. Our knobs sit very close to the secondary housing so the factory dust cover should fit fine. However, if the knobs contact the secondary housing before the screws reach the secondary mirror, we can supply knobs with longer screws at no charge. If the knobs interfere with the dust cover a shower cap can be used as a substitute cover.
2. These knobs will not fit the VC200L, which requires different knobs (see Item VC200sec).
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.
