My 2" 1 1/4" Howie Glatter Holographic collimator arrived last Friday along with the TuBLUG accessory.
The total cost was $468 + postage.
The TuBLUG has a barlow lens built into it.
Straight out of the bolt case and into a v block to confirm the laser was centered as it was,No problems there.
It came with 2 annulus rings which i don't need as my primary is already centered, 1 Holographic lens that projects a square grid pattern with the dot in the centre.
The units are huge.
My scope is now collimated in the lounge room all i have to do now is get it out into the field.
