How to Collimate a Newtonian Telescope │ astrobiscuit tutorial
This is a guide to Collimating Newtonian Telescopes in the daytime using a collimation cap, a Cheshire eyepiece and a laser collimator (I also run through collimating the laser collimator!). I personally use a collimation cap followed by a collimated laser collimator for my daytime collimation. This basic tutorial is all you need to get great collimation of your newtonian or dobsonian telescope. In my follow up tutorial I run though more advanced topics such as how to check if your telescope is mechanically sound as well as running through night time collimation using the stars.
