Page 14: Collimating The Optics
COLLIMATING THE OPTICS Collimation is the process of aligning the telescope’s optics. It is easiest to collimate a telescope during the day with Dobsonians use the Newtonian refl ector optical design, the telescope pointed toward a blank wall. This will provide which consists of a parabolic primary mirror and a fl at a high-contrast view, making it easier to determine which secondary mirror. - Page 15 a. Adjust one set screw at a time. Make only small For the 8” Dobsonian, use the 2.5mm hex key and adjustments. Phillips head screwdriver to tilt the primary mirror. There are three pairs of collimation screws. Each pair works together b.
