Explore Scientific 2-in HR Coma Corrector
Explore Scientific 2" HR Coma Corrector
If you have a Newtonian telescope, you know what coma is… the comet-shaped distortion that 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. Explore Scientific’s Harrie Rutten Variable 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 M48x0.75 threaded adapter that will allow you to secure to your T-adapter.
