Explore Scientific 2” HR Coma Corrector

If you have a Newtonian telescope, you know what coma is…that comet-shaped distortion stars near the edge of the field suffer from, especially with today’s fast Newtonian reflectors. A coma corrector is the answer if you wish to minimize this off-axis optical phenomenon, and Explore Scientific’s HR Coma Corrector is a good choice for Newtonians with a 2” focuser.

The optics inside the black-anodized aluminum barrel of the Explore Scientific 2” Coma Corrector are multi-coated to reduce reflections and increase contrast. The top of the corrector has three over-sized thumbscrews to hold your eyepiece or other 2” accessory firmly in place. A rubber grip lies just below the thumbscrews, and it is textured to help you keep a firm hold when changing eyepieces or adapters, even with your gloves on.

Speaking of adapters, the Explore Scientific HR Coma Corrector comes with two of them - an M42x0.75 and an M48x1 threaded adapter that will allow you to secure a standard or oversized t-ring to the corrector.
