M13 Croped688 viewsFirst Astrophotograph taken.
St2000XCM-M33 10-13-07543 viewsThis is a single 10 minute image. It shows better detail than the last one, just not enough signal.
ST2000XCM-M17525 viewsThis is 2x10 minute images taken on 13Oct. Much more detail than the last time.
Mars Attacks!597 viewsMars, 11/10/07 ~1139 UT, 6" SCT @ f25, NexImage, 674 frames, Registax 4.0.1. Arcadia Tharsis, Chryse regions. 92.4% illuminated, 13.1 arc sec dia.
Eclipse of the Moon928 viewsA series of photos of the lunar eclipse of Dec 21th showing the shadow of the earth traveling across the Moon's surface. Images taken with a 130 mm f/8 Astro-Physics refractor and a modified Canon 40D DSLR at ISO 200. Exposures varied from 1/2000 th of a second at the begining of the eclipse to 6 seconds at totality.
Rosette Nebula591 viewsThe Rosette Nebula is a large, circular stae forming region located near one end of a giant molecular cloud in the bonstellation Monoceros. The nebula lie at a distance of ~ 5,200 light years (?) and measure ~ 130 light years in diameter. Taken with a Tak FSQ-106, SBIG STL-11000 on a Paramount. Single 30-min exposure using the Tzec Maun scope in Australia.
Messier 13-Globular Cluster in Hercules551 viewsWe were showing a number of globular clusters at our star party events at Oliver Lee State Park. Here is an image of M (Messier) 13 taken with the 6" SCT and a Canon Rebel XSi (15 min). (retouched after I got a new monitor)
The Great Nebula in Orion1150 viewsMessier 42 in the constellation Orion is a star forming region in our galaxy, the Milky Way. It is a difficult object to photograph because of it's large variation in brightness. The attached is an image of M42 that is a combination of multiple stacked 10 second, 30 second, 60 second, 150 second, and 300 second exposures using Photoshop's High Dynamic Range tool ( Canon 20Da DSLR and an Astro-Physics 130mm f/8 refractor).
The Crescent Nebula and surrounding nebulosity662 viewsThe Crescent Nebula (NGC 6888) is in the constellation Cygnus. The brighter portion of the surrounding nebulosity in the upper left is IC 1318, which is part of the gamma Cygnus nebulae complex. The bright star in the center of the Crescent Nebula is a Wolf-Rayet star, which are extremely luminous and hot stars that loose mass at very high rates, designated as HD 192163. The image is a total exposure of 1 hr 45 min (21 X 300 sec) taken with a Takahashi E-180 f/2.8 astrograph and Canon 20Da DSLR camera.
Lunar Eclipse620 viewsImage of the Lunar eclipse on Dec 21, 2010 at 1:17 AM from Mayhill, NM. Although the Moon is in the Earth's full shadow, or umbra, the moon appears to be have a copper-colored glow. This coloration is due to light bent (refraction) or scattered by the Earth's atmosphere onto the Moon. Image is a 6-second exposure with a Canon 40D at ISO 200 through a 130 mm f/9 Astro-Physics refractor on a Paramount.
The gamma-Cygni Region572 viewsThe area around gamma-Cygni (in the constellation Cygnus) is surrounded by a large nebulous region collectively known as IC 1318. The brightest star in the image, gamma-Cygni or Sadr, is a foreground star and is not part of the nebula. Due to the dark lane dividing the nebula, it is sometimes referred to as the Butterfly Nebula. The image is a total exposure of 1 hr 15 min (15 x 5 min lights, 30 x 5 min darks, 64 flats; Takahashi E- 180, Canon 20Da, Paramount).
The Moon661 viewsThe Moon, our nearest neighbor, provides a wealth of detail even in small telescopes. Indeed, as Garrett Serviss wrote regarding the distance to the moon in his book "Other Worlds" in 1901: "In consequence, of course, of its nearness, the moon is the only member of the planetary (solar) system whose principal features are visible to the naked eye." Image taken with a Astro-Physics 130 mm f/8 refractor and a Canon 20Da DSLR (11 X 1/250 second exposures at ISO 200; aligned and combined in Images Plus).
