Messier objects by John Sefick

John Sefick's images of Messier objects

John Sefick has obtained his images with a 25-inch Newtonian reflector and a ST-6 CCD camera. The location was a cabin near the Chequamegon National Forest in Northern Wisconsin. The telescope was mounted on an equatorial platform produced by Equatorial Platforms of Nevada City Californiai - see their image collection by different astrophotographers. The ST-6 camera has a Santa Barbara Instruments color wheel attached to the front of the camera. The telescope is an Obssession f5 focal length with Torus Precision Optics (of Iowa City).
