Messier_27.jpg
Messier 271360 viewsM 27 , aka the dumbbell nebula, in the constellation Vulpecula was discovered by Charles Messier in 1764. M27 is a large cloud of expanding gas, which is the remains of a star that expelled its outer atmosphere near the end of its lifetime. M27 is a bright object that can be seen in binoculars and is a favorite telescopic object in the Spring and early Fall. Total exposure of 1 hr 40 minutes (20 x 5 min lights;30 darks; 66 flats; AP 178 f/9 refractor; Modified Canon 50D; AP 1200 mount; guided exposures)
M95_2012_03_22_6SCT_16IC_32min_SN2012aw.jpg
Supernova in M951355 viewsA Type II supernova recently exploded in M95, a galaxy approximately 33 million light years away. Type II supernova are generated when large massive stars "die" and blow up. Heavier elements such as iron, gold, silver and uranium are created in about a second then scattered into the cosmos. The supernova is still about magnitude 13 so its still pretty dim (given its large distance). Imaged using a 6" SCT at f6.3 using an Atik 16IC camera (32 min exposure).

2011_10_03_Whitelight_CaK_composite.jpg
What a diiference a filter makes!1347 viewsHere is the Sun taken on 10/3/11 at 11:15 AM first in White light (left) and Calcium K (right) using a Stellarvue 80ED. The white light image shows a few sunspot groups while the CaK image shows much more detail and areas of increased magnetic activity. AR1302 is on the far right, nearly rotating out of view. The white light image was taken using an Orion glass filter and single snapshot from a Canon T2i. The CaK image was taken with an Imaging Source camera and Lunt B1200 CaK filter.
IC_410_and_the_Tadpoles.jpg
IC 410 and the Tadpoles1347 viewsIC 410 in the constellation Auriga is a nebula associated with the open cluster NGC 1893. On close examination, the two "tadpoles" can be found "swimming in the gaseous nebula." IC 410 imaged with a Canon 20Da DSLR and Takahashi Epsilon 180 f/2.8 astrograph on a Paramount.
Lunar_Eclipse_0117_am.jpg
Lunar Eclipse1347 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.
Messier_82_Total_exposure_685_minutes.jpg
Messier 82, a starburst galaxy1345 viewsMessier 82, a galaxy in the constellation Ursa Major, was discovered by Johann Elert Bode in 1780. Today we know M82 is a starburst galaxy where a large number of new stars are being born. Large amounts of in-falling gas are excited by the newly formed stars and are responsible for the red Ha emissions Total exposure was 11.4 hours (137 x 5 min lights) taken with a 130 mm f/8 Astro-Physics refractor and SBIG ST 2000xcm CCD camera on an Astro-Physics 1200 mount. Processed in Images Plus 4.5 and Adobe Photoshop CS5

Abell_21_and_NGC_2395.jpg
Abell 21 and NGC 23951337 viewsAbell 21 and the sparse open cluster NGC 2395 (upper left...a few bright stars distinguish it from the star field....barely) are found in the constellation Gemini. Image taken with a modified Canon 40D DSLR and a Takahashi E180 f/2.8 astrograph on a Paramount. Total of 11 hr 20 min exposure (136 x 5 min lights, 30 darks, 64 flats, 64 flat darks) and processed with Images Plus 5.0, PixInsight 1.7, and Adobe Photoshop CS6.
Thors_Helmet.jpg
Thor's Helmet in the winter Milky Way1335 viewsNGC 2359 or Gum 4, a.k.a. Thor’s Helmet, is found in the winter Milky Way of the constellation Canis Major (the large dog). This constellation is easily located since Sirius, the brightest star in the sky, is found in Canis Major. Thor’s Helmut is a gaseous nebula illuminated by a very hot Wolf-Rayet star. Image is a total of 2.75 hr exposure (33 x 5 min lights, 30 darks, 64 flats, 64 dark flats) taken with a modified Canon 40D DSLR and Takahashi E-180ed astrograph.
NGC_1499_small.jpg
NGC 1499 California Nebula1334 viewsThe California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the state of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1,000 light years from Earth. This is a Ha, G, B exposure.
