Skylabs Mirror Spotting Template and Center Spots
Accurate Collimation tool for Newtonian Telescopes
The collimation (alignment) of the mirrors of the telescopes is extremely important for visual observation. In the case of really fast telescopes (focal ratio < 5) and astrophotography, the collimation becomes critical.
The Skylabs Mirror Spotting Template and Center Spots will help you to align the optical axes of your Newtonian telescope. In addition to those items, you also need a laser collimator and/or a Skylabs Cheshire Eyepiece if you want a really good image quality.
Important note: Single beam laser collimators are relatively affordable and easy to use. Unfortunately, they can not help to correct the off-axis position of the secondary mirror or ensure the collimation of the surfaces of both mirrors. While the laser collimator really helps to speed up the process, in order to ensure the perfect collimation between the two mirrors, a Cheshire is always required.
The mirror spotting template and center spots are required for those mirrors without a center spot. Select the right size of your spot and template. Request the small triangle for 1.25” Cheshire eyepiece or the big one for 2” Cheshire. Obviously, if you have a 2” focuser a 2” Cheshire eyepiece is highly recommended.
