Kurt, it seems to me that you can't use the Blug on a closed-tube Newtonian, since you can't see it. Am I off the mark here? On Mon, Apr 21, 2008 at 1:33 PM, Canopus56 <canopus56@yahoo.com> wrote:
In addition to Glatter's collimator, I also recommend Glatter's blug, if you are collimating a fast Newt. It greatly simplifies the laser collimation process for planar holographic alignment.
