Description

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. Our 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.

Kevin ★★★★★

My outer-edge stars look like actual stars now instead of little seagulls, and the coma correction held up even at f/4.5. I was worried about adding another piece of glass to the train, but the image stayed crisp with no visible halos. First clear night with it and I re-processed two old data sets j

James ★★★★★

The stars across my entire frame are now razor sharp, even at f/4. This little corrector threaded right onto my 2" focuser without any extra adapters needed. Definitely worth the investment for anyone shooting with a fast Newtonian.

Sebastian ★★★★★

I was worried about coma in my fast Newtonian, but this corrector really sharpens stars across the whole frame. The threaded connection screws on smoothly and holds alignment perfectly. My wide-field shots finally look crisp from edge to edge.
