Howie Glatter 1.25" TuBLUG Newtonian Laser Collimator
When it comes to lasers and collimation, one of the most trusted names in the business is guru Howie Glatter. His uncompromising quality and dedication to above average products, not only put his name above the rest - but in demand as the finest available on today's market. Usually a manufacturer doesn't take the time to explain to a customer exactly why their product excels over others - or why it performs better - but not Howie. Here's what he has to say about his new Howie Glatter 1.25" 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. It's a Blug (Barlowed laser plug), containing its own lens and shadow screen that fits within a side cut-out tube, the combination being known as a tuBlug. Like the collimator self-Barlow attachment or the Blug, 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."
Unfortunately, the standard Blug which fits to the inner end of the focuser drawtube inside the telescope, can not used as 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."
