Center Spot A Primary

Postby Dion » Mon Sep 20, 2010 11:15 am

I replaced the primary center spot on my primary with one of the new fangled 'hotspot' centers to fit in with some experimentation I'm doing with collimating, however this will also apply if you have a mirror 'without' a center spot and need to add one.

Firstly, these are the 'hotspot' centers, there are a few design feature of this particular type, firstly the 'spokes' point at your 3 collimation bolts when fitted properly, aiding alignment using a collicap. Secondly they are reflective, meaning they project better in multi mirror situations, especially if used with an autocolimater, thirdly they aren't symetrical like the normal ring, which is of benefit again if using an autocollimater.

This is what they look like :-
