The gamma-Cygni Region714 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).
Messier 13-Globular Cluster in Hercules711 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)
M51 Whirlpool Galaxy703 viewsThis was my second ever shot. Needs alot of work. But I did get some detail.
Markarian's Chain703 viewsMarkarian's Chain is found in the constellations Coma Berenices and Virgo. The two brightest members are Messier 84 and 86 in the upper right hand portion of the photo. The two galaxies close in proximity below them are known as the "Eyes." The one that is very irregular in shape is NGG 4438 (also cataloged as Arp 120 in Arp's Catalog of Peculiar Galaxies) that as been suggested to be the result of the in-progress merger of two galaxies. 2.6 h (32 x 300 sec) total exposure; Takahashi E-180; Canon 20Da
Mercury Transit 1 - Nov. 8, 2006702 viewsThis shot was taken near the end of its transit.
Messier 27 through Ha, OIII, and SII filters693 viewsMessier 27 is a nebula found in the constellation Vulpecula, often shown in the summer and early fall at our Oliver Lee star parties. This image is through narrowband filters, where Hydrogen alpha is mapped to green (2 hr 25 min combined exposure); Oxygen, OIII, is mapped to blue (3 hr 15 min combined exposure), and Sulfur, SII, is mapped to red (5 hr 40 min combined exposure); taken with a Takahashi FSQ106ED and SBIG ST2000xm camera with Baader filters.
Lunar eclipse - August 28, 2007687 viewsSelection of seven pictures from about 350 taken during the event. Taken with Canon Rebel 350D XT and a tripod, that's it!
The Ringed Planet683 viewsSaturn is the 6th planet from the Sun at a distance of about 900 million miles. The rings are composed primarily of water ice with particles the size of snowflakes up to house-sized boulders. The rings extend almost 50,000 miles above the planet and average about 60 feet thick (paper thin indeed). To learn more about Saturn, go to our "PLANETS" page. Celestron C9.25 at f25, Imaging Source 21AU618 color camera.
Messier 15682 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).
Rosette Nebula681 viewsThe Rosette Nebula (NGC 2237-8, 46) and the open cluster NGC 2244 in the center of the nebula is found in the constellation Monoceros. The nebula is one of the largest in the sky. The nebula was photographed with a Takahashi E-180 astrograph and Canon 20Da (ISO 800); Exposure was a total of 2.5 hours (30 x 300 seconds), calibrated, aligned, and stacked in Images Plus and processed in Photoshop CS4.
M57680 viewsMessier 57 the Ring Nebula appears in the northern constellation of Lyra is a prominent example of a planetary nebula. This is a shell of ionized gas expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf. The distance is 2300 light years.
The Active Sun in Hydrogen Alpha679 viewsThis image was taken through a 40mm Coronado PST of the Sun on 12/27/2011 at 1925UT. The photograph is centered on the hydrogen alpha emission line at 656.28 nanometers (nm) and shows the chromosphere. Active Region 1384 is the dark region near the center of the photograph. A very large prominence is seen erupting along the rim of the Sun on the right.
