My thoughts on this product
Fantastic piece of equipment. This is much better for collimation of my SCT scope than a pinhole poked in a piece of paper or foil. It just works great. I did make a holder for it to keep it from rolling off an old photo tripod I use just for this p...

BEST OF THE BEST
I tried cheaper laser collimators, with dissapointing results. The Glatter laser is a precision made instrument. If your serious about astronomy, use a Glatter laser collimator. Glatter lasers are not cheap, but you get what you pay for!

MONEY WELL SPENT !!!
Yes, it is expensive. But, you get what you pay for! I use to use a cheshire collimator, and thought it was accurate. Was I wrong. The TuBlug, uses a barlow lens. The Barlowed technique of collimating the primary lens, is much more accurate. I now ...

Works as designed
I added this 1.25" mirror to my kit so that I would have both size mirrors available if anybody in our club needed them. So far so good.

Hubble Artificial Star
Needed to collimate a new C8 OTA that was pretty far out of center, probably due to being knocked about in transit. Much more convenient to do indoors with a little light than outside in the dark. Did inside warehouse at work on a Sunday, so had plen...

Works great, just need to
Works great, just need to be far away from telescope. A not in full sun, makes it hard to see the light. But works great when you can get the light far away and about twilight brightness.

Tried collimating using stock Phillips head screws, very cumbersome. Bob's Knobs worked as advertised, quick and easy.

Works as it should however led is too dim to use in daylight on any but a small refractor that can be placed close enough. Minimum focus distance is too great on any reasonably sized reflector or SCT / RC for daytime use. only useful at night or clos...

Should have done this years ago
I installed this set of Bobs Knobs after owning my Celestron 9.25 for nearly 20 years. I've always been afraid to collimate with a screw driver. The knobs have made it simple, and it's better aligned than it has been in years. Easy to insta...

this collimator is adequate and very well aligned. Excellent for the price. It is not what I would consider fine instrument quality, but the results are indistinguishable from a $250 collimator that I borrowed.
