IC_1275_2012_05_20_71FL_XS_120min_iso800_-_Cropped.jpg
IC 1275 region771 viewsIC (Index Catalog) 1275 is an emission nebula located within a rich star field in the constellation Sagittarius. The red color is due to ionized hydrogen gas (HII regions) being excited by nearby stars. Image taken through a Borg 71FL and modified Canon XS DSLR (two hour exposure, stacked with Nebulosity and processed in Photoshop).
Supernova_in_Messier_101_(9_5_2011).jpg
Supernova in Messier 101767 viewsA supernova has appeared in the galaxy designed Messier 101. A supernova is essentially a star at the end of its lifetime that has exploded. This particular type of supernova is a type Ia, which is assumed to be due to the destruction of a white dwarf in a binary star system. The supernova can be seen in the image as the brightest "star" within the galaxy; located to the left of the center of the galaxy.
M65_M66.jpg
M65 and M66764 viewsM65 and M66 are two galaxies in the constellation Leo. Photographed using a Takahashi FSQ 106ED and a Canon 20Da DSLR. Exposure time was 27 minutes (9 X180 sec); calibrated, aligned, stacked, and DDP stretched in Images Plus followed by Adobe Photoshop CS4.
Annular_Eclipse_Albuquerque_5_20_2012.jpg
Annular Eclipse of the Sun761 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).
IC_1275_and_NGC_6559.jpg
IC 1275 and NGC 6559761 viewsIC 1275 and NGC 6559 lie in our Milky Way galaxy in the constellation Sagittarius close to Messier 8. This complex area of both emission and reflection nebulosity also includes IC 1274, IC 4684, and IC 4685. The image is a total combined exposure of 1 hr 25 min with a Takahashi E-180ED astrograph and a modified Canon 40D on a Paramount. Processed using Images Plus and Adobe Photoshop.

North American Nebula761 viewsNorth American Nebula (NGC 7000) in Cygnus. A 3-minute exposure taken with a Takahashi Epsilon 180 f2.8 and a Canon 20Da DSLR (ISO 800)
Moon_2011_09_06_1.jpg
Moon: Tyco/Clavius crater region759 viewsAn image of the Tyco/Clavius region taken from Alamogordo. Tyco (53 miles in diameter, near center of image) is a relatively young crater based on samples from Apollo 17. Clavius (140 miles in diameter, lower center) is a much older crater with several smaller craters inside of it. Image taken using the C9.25 with a Imaging Source DMK41AU02 camera and Lumicon H-alpha filter. This picture is surprisingly similiar to one in the Sep/Oct 2011 SkyNews (p.36).

The Hale 200-inch telescope757 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.
Messier_81_in_Ursa_Major.jpg
Messier 81 in Ursa Major753 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. The image was taken with a 130 mm f/8 Astro-Physics refractor with a total combined exposure of 7 hrs 40 minutes (92 x 5 min lights; 30 darks; 64 flats; SBIG ST 2000xcm @ -25 0C; AP 1200 mount)
IC443_The_Jellyfish_in_Gemini.jpg
The Jellyfish 738 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.
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars738 viewsHere are basic spectra from two familiar stars in the night sky. Vega's spectra is on the left and basically has weak spectral lines based mostly on the Hydrogen Balmer series. This is indicative of a fairly young, hot star. Betelgeuse's spectra is far more complex. We can see spectral lines for Barium, Calcium, Iron and Magnesium and compounds like Vandium Oxide and Titanium Oxide indicative of a star near the end of its life. Data collected with amateur equipment and processed through RSpec software.
M42n=30EXP2minCombineFilesSigAvg.jpg
M42 in Orion735 viewsImaged with a 178mm f/9 Astro-Physics refractor and a Canon 20Da (ISO 800) on a Paramount. Total of 30 two-minute exposures aligned, collimated, and combined in Images Plus and processed in Adobe PhotoShop CS2. Exposures were keep short to preserve detail near the bright core of the nebula.
