    Horsehead and Flame Nebula

    The Horsehead (Barnard 33) and Flame Nebula (NGC 2024) are about 1,400 light years away in the constellation Orion. Part of the Orion complex, the dark cloud of gas and dust is a region where star formation is taking place. Color images are created by taking individual images with a monochrome camera through separate hydrogen alpha, red, green and blue filters. Since the objects have very low brightness, multiple long exposures are used to create the final image. A tracking mount that compensates for the earth's rotation prevents star trailing during the long exposures. Camera Santa Barbara Instuments Group STL11000M Telescope Astro-Physics 130mm EDFS f6 Focal Length 780mm Aperture f6 Exposure Time Hydrogen Alpha 5 x 30 min (total 5.5 hr.)

  • Bode's Galaxy

    Bode's Galaxy

    ColBode's Galaxy (Messier 81) is a grand design spiral galaxy about 12 million light years away in the constellation Ursa Major. Fun fact, light travels almost 6 trillion miles in a year. The light you see when looking at M 81 or capturing with a camera left it 12 million years ago. Color images are created by taking individual images with a monochrome camera through separate luminance, red, green and blue filters. Since the objects have very low brightness, multiple long exposures are used to create the final image. A tracking mount that compensates for the earth's rotation prevents star trailing during the long exposures.

  • Running Man and Orion Nebula

    Running Man and Orion Nebula

    The Running Man NGC 1977) and Orion Nebula (Messier 42) are visible to the naked eye about 1,400 light years away in the constellation Orion. They are the closest region of active massive star formation to Earth. Color images are created by taking individual images with a monochrome camera through separate luminance, red, green and blue filters. Since the objects have very low brightness, multiple long exposures are used to create the final image. A tracking mount that compensates for the earth's rotation prevents star trailing during the long exposures. Camera Santa Barbara Instuments Group STL11000M Telescope Astro-Physics 130mm EDFS f6 Focal Length 780mm Aperture f6 Exposure Time Luminance 9 x 5 min (total 1.75 hr) Red 4 X 5 min Green 4 x 5 min Blue 4 x 5 min Taken 2/26/2009 Image by Tom Auchter

  • The Eyes Galaxies

    The Eyes Galaxies

    The Eyes Galaxies (NGC 4435 and NGC 4438) are gravitationally interacting lenticular galaxies about 52 million light years away in the constellation Virgo. Also in the image are a near edge-on spiral galaxy (NGC 4402), an elliptical galaxy (Messier 86) and other faint galaxies. All are members of the Virgo Cluster of up to 2,000 galaxies. Color images are created by taking individual images with a monochrome camera through separate luminance, red, green and blue filters. Since the objects have very low brightness, multiple long exposures are used to create the final image. A tracking mount that compensates for the earth's rotation prevents star trailing during the long exposures.

  • Lunar Mid-Eclipse

    Lunar Mid-Eclipse

    On average total Lunar Eclipses occur every 2.5 years due to the tilt of the lunar orbit. Sunlight filtered and refracted by the Earth's atmosphere turns the Moon a deep orange red color. Telescope Astro-Physics 130mm EDFS f6 Focal Length 780mm Aperture f6 Image by Tom Auchter
