Eight_hr_total_exposure.jpg
The Seven Sisters1357 viewsThe star cluster Messier 45 in the constellation Taurus is popularly referred to as the Pleiades or Seven Sisters. The blue color of the reflection nebulosity is due to the blue light of the brightest stars being scattered by the surrounding dust. The pink tones in the right hand portion of image are due to weak emission of a gaseous component. Total combined exposure is eight hours with a modified Canon 40D DSLR at ISO 800 and a Takahashi Epsilon 180 f/2.8 astrograph (96 x 5 min lights; 64 flats; 30 darks; Paramount; Images Plus and Adobe PhotoShop CS5).
Supernova_in_Messier_101_(9_5_2011).jpg
Supernova in Messier 1011380 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.

Messier 8, 20, and 211195 viewsThe Messier objects M8 (large nebula on right), M20 (blue and red nebula upper left) and M21 (open cluster below and to the left of M20) are favorite summer objects in the constellation Sagittarius. The Messier objects are found in a dense star field of our own Milky Way galaxy. Image taken with a modified Canon 40D and Takahashi E-180ed astrograph on a Paramount (50 x 5 min lights; 30 darks, 64 flats).

The Eagle Nebula1700 viewsThe open cluster Messier 16 and the associated nebulosity IC 4703 are found in the constellation Serpens Cauda. The popular name of this object is the Eagle Nebula, and contains the "Pillars of Creation" that was made famous in the image taken by the Hubble Space Telescope. This image was a total of 3.5 hours exposure (21 x 10 min subframes) taken with a modified Canon 40D and a Takahashi Epsilon-180ED.

M15 Globular Cluster in Pegasus1317 viewsMessier 15, a gobular cluster in Pegasus, which was originally discovered by Maraldi in 1746 and rediscovered by Messier in 1764, lies 30,600 light years away. Fourteen 120-second exposures aligned, calibrated, and combined in Images Plus; processed with Adobe Photoshop CS2; taken with a 178mm f/9 Astro-Physics refractor and a Canon 20Da DSLR camera (ISO 800).

Trifid Nebula (M20) in Living Color!1354 viewsHere is another summertime favorite, the Trifid Nebula (Messier 20) done with a Takahashi Epsilon 180 (f2.8) with SBIG 2000 single shot color camera using the Tzec Maun scopes in Australia. This is a single 10-minute exposure.
M33.jpg
M33 -Triangulum Galaxy1067 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.
CombineFilesSigAvg_DDP_GXT_CS4_3.jpg
M171355 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.
M13_5_26_09_15_min_DSLR.jpg
Messier 13-Globular Cluster in Hercules1164 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)
M8_04_01_11_80mm_XS_DSLR_12_min_-_Copy.jpg
Sagittarius Triple Whammy1954 viewsMessier 20, the Trifid Nebula is seen in the upper left. M20 is a combination emission nebula (pink), reflection nebula (blue) and dark nebula (the spider legs in the pink). Towards the center is Messier 8, or the Lagoon Nebula. M8 is an emission nebula and active star forming region. A star cluster is superimposed on it. The lower right has the star cluster NGC 6544. Image was taken using an 80mm Onyx refractor and a modified Canon XS DSLR. Too bad it was only 12 min - I ran out of night,

The Great Nebula in Orion1874 viewsMessier 42 in the constellation Orion is a star forming region in our galaxy, the Milky Way. It is a difficult object to photograph because of it's large variation in brightness. The attached is an image of M42 that is a combination of multiple stacked 10 second, 30 second, 60 second, 150 second, and 300 second exposures using Photoshop's High Dynamic Range tool ( Canon 20Da DSLR and an Astro-Physics 130mm f/8 refractor).
Markarian_s_Chain.jpg
Markarian's Chain1154 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
