Omegon Pro Coma Corrector for Astrograph: round stars right to the corners of your astrograph<\/strong><\/h2>\n\n\n\n

A fast Newtonian produces coma: stars off-center stretch into little comets, and the faster the f-number, the worse it gets. With an f\/4 astrograph, that is visible in every corner of the image without a corrector.<\/p>\n\n\n\n

This corrector eliminates coma. It fits into the 2-inch focuser and projects a corrected, flat field onto the sensor, keeping stars round right to the edge.<\/p>\n\n\n\n

For Newtons up to f\/4<\/h4>\n\n\n\n

The two-element lens system is designed for fast mirrors down to f\/4. The 75 mm back focus provides room for a filter wheel or filter drawer between the corrector and sensor.<\/p>\n\n\n\n

Connections complete<\/h4>\n\n\n\n

The camera side is M48 and a T2 adapter is included, so both astronomy cameras and DSLRs with a T2 ring connect directly. The filter thread accommodates a 2-inch filter.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

For Newton telescopes and astrographs up to f\/4 with a 2-inch focuser. Measure the distance from corrector to sensor at exactly 75 mm for the best result.<\/p>\n\n\n\n
