About the Explore Scientific HR Coma Corrector for Newtonians... After hours at the eyepiece, you finally get to view the fruits of your astrophotography labors. The stars in the c enter 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. The Explore Scientific Coma Corrector can help you minimize or even eliminate image aberrations caused by this off-axis optical phenomenon even in fast Newtonians. The 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.
