Messier_82_Total_exposure_685_minutes.jpg
Messier 82, a starburst galaxy1221 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
Messier_15.jpg
Messier 151123 viewsThe globular cluster Messier 15 is found in the constellation Pegasus. Globular clusters are large typically spherical clusters of stars gavitationally bond together. Current estimates suggest M15 contains at least 450,000 solar masses with a very dense center. Image taken with a 178 mm f/9 Astro-Physics refractor and a modified Canon 50D DSLR on an Astro-Physics 1200 mount (70 x 60 sec lights; 30 darks; 66 flats; Images Plus and Adobe Photoshop CS5 software).
IC443_The_Jellyfish_in_Gemini.jpg
The Jellyfish 1412 viewsIC 443, aka The Jellyfish, is a large supernova remnant in the constellation Gemini. Our current understanding is that IC 443 is the remnants of a Type II supernova, the ultimate fate of a massive star, which occurred approximately 3000 to 35,000 years ago. Image is a total of 7 hr 15 min exposure (87 x 5 min lights, 30 darks, 64 flats, 64 dark flats; modified Canon 40D; Takahashi E180ED astrograph; Paramount) processed with Images Plus 4.5; PixInsight; Photoshop CS6.
Annular_Eclipse_Albuquerque_5_20_2012.jpg
Annular Eclipse of the Sun1380 viewsAnnular eclipse of the sun on May 20, 2012 between 7:33:39 – 7:38:05 pm MST (DST in effect) was photographed near Albuquerque, New Mexico in the Cibola National Forest by Sandia peak at an elevation of 6559 feet. The image was taken through Baader solar film with a Nikon D100 DSLR with a Nikon ED 70-300 lens @ 300 mm ( 1/60th second exposure at ISO 200).
Messier_78_region_in_the_constellation_Orion.jpg
Dust lanes around Messier 782181 viewsMessier 78 is a reflection nebula in the constellation Orion. As the name “reflection nebula” implies, M78 shines by the reflection of light from surrounding stars. Long photographic exposures show the dust lanes that are near the nebula. The red area in the lower right hand corner of the photograph is part of Barnard’s loop.... a large loop of excited hydrogen gas. Total combined exposure of 11.5 hours (138 x 5 min lights, 35 darks, 64 flats, 64 flat darks); Takahashi E-180ED astrograph; Canon 40D modified.
Galaxies_in_the_Constellations_Virgo_and_Coma_Berenices.jpg
Galaxies in Virgo and Coma Berenices1403 viewsMany galaxies are seen in the constellations Virgo and Coma Berenices. To the bottom left is seen the spiral galaxy Messier 88, in which young stars and active star formation are present. In the lower right corner is seen the elliptical galaxy Messier 87, whose golden brown coloration is suggestive of old stars and little if any star formation. In the upper right hand quadrant is a pair of galaxies, NGC 4438 and 4435, aka the Eyes or Arp 120. Exposure is a total of 13 hr 35 min (163 X 5 min).
Thors_Helmet.jpg
Thor's Helmet in the winter Milky Way1220 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.
Venus_Transit.jpg
Venus transit in white light1441 viewsThis image of the Venus transit was taken in white light (compare to image on right) through a Baader solar filter. Image taken with a TeleVue 3” f/7.4 Oracle refractor using a Baader flat field Barlow to extend the focal length (approximately f/27) and a Canon 50D DSLR @ ISO 400. Three exposures of 1/400 sec were combined and processed in Image Plus 4.50 and Adobe Photoshop CS5.

Spiral_Galaxy_M101_in_Ursa_Major.jpg
Messier 101 in Ursa Major1470 viewsMessier 101, aka the Pinwheel Galaxy, is a spiral galaxy in the constellation Ursa Major. In the spiral arms of the galaxy are many blue areas of active star formation as well as red HII regions. The image is a total combined exposure of 5 hours 25 minutes (65 x 5 min lights, 30 darks, 64 flats) with an SBIG ST2000XCM camera and an Astro-Physics 130mm f/8 refractor.Aug 11, 2012

Messier 81 in Ursa Major1413 viewsM 81 is a spiral galaxy in the constellation Ursa Major was discovered by Johann Elert Bode in the 18th century. Current estimates indicate M 81 is approximately 11 million light years away. The dim companion galaxy Holmberg IX (UGC 5336) can be seen as a small blue smudge above M 81.
