The gamma-Cygni Region604 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).
M51 Whirlpool Galaxy598 viewsThis was my second ever shot. Needs alot of work. But I did get some detail.
Messier 13-Globular Cluster in Hercules593 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)
Mercury Transit 1 - Nov. 8, 2006585 viewsThis shot was taken near the end of its transit.
Lunar eclipse - August 28, 2007581 viewsSelection of seven pictures from about 350 taken during the event. Taken with Canon Rebel 350D XT and a tripod, that's it!
St2000XCM-M33 10-13-07581 viewsThis is a single 10 minute image. It shows better detail than the last one, just not enough signal.
Markarian's Chain580 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
ST2000XCM-M31578 viewsThis is a single 10 minute image. I was working on my guide setup and tested it out on this object.
Messier 27 through Ha, OIII, and SII filters578 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.
NGC 6820 and 6823577 viewsNGC 6823 is an open cluster in Vulpecula, whose center contains 9th magnitude stars along with fainter members that is immersed in the faint emission nebula NGC 6820. Photographed with a Takahashi Epsilon 180 f/2.8 and Canon 20Da DSLR on a Paramount (Ten 5-minute exposures at ISO 800; calibrated, aligned, combined and processed in Images Plus V 3.80 (DDP stretch) followed by Adobe Photoshop CS4).
Messier 15576 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).
M57573 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.
