M33 -Triangulum Galaxy63 viewsThe Triangulum Galaxy (Messier 33 or NGC 598) is a spiral galaxy approximately 3 million light-years away. It is the third largest galaxy in the Local Group, a group of galaxies that also contains the Milky Way. M33 is about 60,000 light years across and contains 10-40 billion solar masses. Celestron 6" SCT, unguided on GC-5. Stock Canon Rebel XSi, 21 minutes (needs more time-but forgot to charge battery). Taken at Dog Canyon State Park on the 11/22/08 public star party.

Lowell Observatory 24" refractor42 viewsThis is a picture of the focuser, RA gauge and knobs of the 1896-vintage 24" Alvan Clark & Sons refractor at Lowell Observatory. Percival Lowell used this scope to make his observations of Mars. V.M. Slipher used the telescope (along with a spectrograph) to determine that the universe is expanding. In the 1960's, NASA used the telescope to scout of landing spots on the Moon.

Cat's Paw Nebula (NGC 6334)95 viewsNGC 6334 (also known as the Cat's Paw Nebula) is an emission nebula about 5,500 light years away in the constellation Scorpius. It was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa. This is a single 10 minute H-alpha exposure from the Tzec Maun Observatory in Mayhill NM.Aug 20, 2010

Antares region98 viewsThis image is of the Antares region in Scopius. The large globular cluster is Messier 4 and the smaller globular forming a triangle with Antares and M4 is NGC 6144. M4 is about 70 light years in diameter and around 10 billion years old. Image was taken with a Canon 20Da DSLR and a Takahashi E-180 astrograph on a Paramount.Aug 17, 2010

M1776 viewsAn image of Messier 17, commonly call the Omega, Horseshoe, or Swan Nebula, in the constellation Sagittarius. There are over 600 stars within this gaseous nebula. The image was taken with a Canon 20Da DSLR at ISO 800 (26 x 5 min light exposures, 35 x 5 min Darks, and 64 lights) and a Takahashi E-180 astrograph. Processed and calibrated using Images Plus 3.80 and Adobe Photoshop CS5.Aug 17, 2010

The Hale 200-inch telescope120 viewsThis summer we took a tour of Mt. Palomar Observatory. The 200-inch (5.08 m) telescope is named after astronomer George Ellery Hale. It was built by Caltech with a $6M grant from the Rockefeller Foundation, using a Pyrex blank manufactured by Corning Glass Works. The telescope (the largest in the world at that time) saw first light January 26, 1949.Jul 27, 2010

Messier 8 region137 viewsThis picture illustrates the area in and around Messier 8 (M8) in the constellation Sagittarius. This region is in the general direction of the center of the galaxy, so there is an abundance of dust and stars! The red regions are concentration of hydrogen gas, the building blocks of future stars. M8 is known as the "Orion nebula of the summer sky". 13 minute exposure (5min Ha, red; 4min blue, 4 min green) taken with the Tzec Maun 106 mm FSQ Tak, SBIG-11000M stacked with Nebulosity, "tweaked" with Photoshop.Apr 25, 2010
