Explore Scientific 2" HR Variable Coma Corrector

After hours at the eyepiece, you finally get to view the fruits of your astrophotography labors. The stars in the center of the field pop like brilliant precise points of light. But as you survey the image, you notice the stars at the edge have taken on an unnatural comet-like shape. Your long night has been marred by coma. Coma is a common plague of the Newtonian reflector design, and its annoying presence at the outskirts of an image can be a bane for astronomers of all levels.

Explore Scientific’s Coma Corrector can help you minimize or even eliminate image aberrations caused by this off-axis optical phenomenon even in fast Newtonians. This 2” coma corrector offers multi-coated lenses, a black-anodized aluminum barrel with spacer markings and a textured rubber grip. Tightly secured by three thumbscrews, this accessory comes with two adapters (.75” and 1”) to secure to your T adapter and a protective cap.
