| Abstract: |
This article from Sky & Telescope offers a guide on how to align and test Newtonian astrographs for optimal performance. Newtonian astrographs are popular among deep-sky imagers but can produce poor star images if not properly aligned. The article suggests using tools like a laser collimator, eyepiece adapter, collimation cap, and machinist's scale, as well as household items like aluminum foil and masking tape, to improve collimation precision. It provides step-by-step instructions on measuring and adjusting the secondary mirror, centering it beneath the focuser, aligning the laser collimator, and adjusting the tilt of the primary mirror and the focuser. The article emphasizes the importance of proper collimation for achieving sharp star images and capturing intricate details in astrophotos. [Extracted from the article] |
