HR Variable Coma Corrector 2 Inch - CC02-00

Description After spending hours at the eyepiece, you're finally ready to behold the results of your astrophotography efforts. The stars at the center of the field gleam as precise, brilliant points of light. However, as you survey the image, you notice that the stars at the edges have taken on an unnatural comet-like shape. This is the telltale sign of coma, a common issue with Newtonian reflector telescopes that can mar an otherwise successful night of stargazing. To combat this, Explore Scientific presents the HR Variable Coma Corrector, a high-performance optical corrector expertly designed by the renowned optical designer, Harrie Rutten. This device is engineered to minimize or even eliminate the image aberrations caused by coma, even in fast Newtonian telescopes. Measuring 2 inches in diameter, the coma corrector is EMC Coated to reduce internal reflections. Its spacer is conveniently marked, allowing you to use it with almost any Newtonian telescope featuring a parabolic primary
