To sum it up collimation is really just two steps:

1. Center the laser in the primary mirror target.

2. Center the primary mirror target's shadow on the BLUG.


That is all there is to it.

I know, we did not use 90 pages of theories, diagrams, or formulas to collimate this telescope. You do not need to know how an internal combustion engine works to drive a car. If the theories of collimation interest you, there are many books on the subject. You will want to check out this book by Vic Menard:

It was any not harder to collimate the f/3.3 telescope used in these pictures than any old f/8 telescope you had as a child. Next time you hear someone saying it is harder to collimate fast telescopes you will be certain that you have much more knowledge than they do about collimating fast scopes. Spread the word.

GRS has much better info on the Glatter tools than does Glatter's own site:

Comments and feedback welcome.

Do you reccommend FLUG over BLUG ?? It is designed to specifically fit the feathertouch.....

I have only heard rumors of the FLUG, but if it is made specifically for the FT, then it sounds like the better choice.

Post a picture if you get one, please.
