Howie Glatter 2" TuBLUG Newtonian Laser Collimator
"The tuBlug is the answer for those who want to Barlow-collimate their primary from the back of the scope, but have a solid tube Newtonian, or can't be bothered to slide their shroud up. The tuBlug is a Blug (Barlowed laser plug), containing its own lens and shadow screen that fits within a side cut-out tube. The combination is known as this product - a tuBlug. Like the collimator self-Barlow attachment, it uses the Barlowed laser principle to project a silhouette shadow of the primary mirror collimation mark back onto its white screen, where the shadow is centered to collimate the primary."
Note to Customer: Unfortunately, the standard Blug which fits to the inner end of the focuser drawtube inside the telescope, can not used as this product - a tuBlug - because it must necessarily have a shoulder which will seat it squarely against the end of the drawtube. The shoulder will be larger than eyepiece diameter, which will prevent the Blug from fitting in the side cut-out tube."

My first Howie Glatter product purchase. I looked at all the popular collimaters and decided on this one since I could find no poor reviews, anywhere. Now I know why. (Posted on 3/8/12)
