About this product
Astro Essentials 1.25" Collimation Cap
A simple, convenient and affordable means of collimating a Newtonian telescope.
Normally when you look down a telescope focuser drawtube it can be hard to tell exactly where to place your eye. When using a collimation cap you will see a bright white circle surrounding your eye pupil, making it easier to centre the primary and secondary mirrors.
Fits firmly into the focuser and provides a highly reflective inner surface.

Collimating cap fits fine, would definitely choose the £6 version looking back as the Collimaton cap isnít very reflective making it a little harder to collimate. Over all though it isnít bad.
