Messier 13-Globular Cluster in Hercules1066 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)
Rosette Nebula1059 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.
Saturn - Webcam1059 viewsThis was shot with a SPC900nc webcam prime focus through my C8 on May 30,2007. This was a stack of 900 out of 1800. Seeing was terrible. Needs better seeing conditions to pull out the ring details.
Lunar eclipse - August 28, 20071046 viewsSelection of seven pictures from about 350 taken during the event. Taken with Canon Rebel 350D XT and a tripod, that's it!
M571046 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.
Mercury Transit 1 - Nov. 8, 20061045 viewsThis shot was taken near the end of its transit.
The Ringed Planet1044 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 27 through Ha, OIII, and SII filters1036 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.
M51 Whirlpool Galaxy1034 viewsThis was my second ever shot. Needs alot of work. But I did get some detail.
Messier 78 in the constellation Orion1034 viewsMessier 78 is a reflection nebula that is a part of a larger complex of nebulae in the constellation Orion . Several other reflection nebulae are seen in the image along with large clouds of dust (dark molecular cloud Orion B). Image is a total of 6 hr 50 min exposure (41 x 10 min lights @ -20 degrees; 20 darks, 64 flats, 64 bias) taken with a SBIG ST2000xcm CCD camera and a TeleVue 140 f/5 refractor on an Astro-Physics 1200 mount. Image acquisition software MaxIm DL; grading, calibration, registration, integration, processing with PixInsight 1.8.2 with final adjustment in Adobe Photoshop CC.
Messier 151031 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).
NGC 6820 and 68231031 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).
