Explore Scientific HR coma corrector

The Explore Scientific HR coma corrector is a coma corrector designed for photographic and visual use. It is an ideal accessory for bright Newtonian telescopes and is recommended by the manufacturer for optics up to f3.

The device stretches the focus of the telescope by only 6% and is 85 mm long, so it is less likely to protrude into the tube. The size of the corrected field of view is 30 mm, so it is recommended for APS-C size sensors. M42 and M48 adapters are available in the standard package for camera mounting.

The manufacturer has taken special care to ensure that the zoom corrector is also visually usable, with visually outstanding image correction and a helical focus adjustment for perfect focusing.
