Sculptor Galaxy331 viewsThe Great Sculptor Galaxy (NGC 253), aka the Silver Coin, in the constellation Sculptor was discovered in 1783 by Caroline Herschel. The galaxy is at a distance of 9.8 million light years away from us. Research on NGC 253 indicates that it is a starburst galaxy, which means that it has recently hosted massive and rapid burts of star formation. The image is a total of 1 hr 50 min (22 X 300 seconds) exposure with a Takahashi E-180 astrograph and Canon 20Da DSLR camera.

NGC 6820 and 6823153 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).

The gamma-Cygni Region223 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).

M15 Globular Cluster in Pegasus192 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).

The Crescent Nebula and surrounding nebulosity314 viewsThe Crescent Nebula (NGC 6888) is in the constellation Cygnus. The brighter portion of the surrounding nebulosity in the upper left is IC 1318, which is part of the gamma Cygnus nebulae complex. The bright star in the center of the Crescent Nebula is a Wolf-Rayet star, which are extremely luminous and hot stars that loose mass at very high rates, designated as HD 192163. The image is a total exposure of 1 hr 45 min (21 X 300 sec) taken with a Takahashi E-180 f/2.8 astrograph and Canon 20Da DSLR camera.

Majestic Jupiter24 viewsJupiter is seen high overhead in Jan 2012 after sunset. This image of Jupiter was taken on Jan 3, 2012 from Alamogordo using a Celestron C6 SCT at f25 (3750mm) and NexImage webcam. Jupiter's moon Io is seen on the left, Europa is on the right. Ganymede is transiting across the face of Jupiter to the lower left. Jupiter has equatorial bands whose colors are generated by churning in its atmosphere. Tinkered with Lucy-Richardson deconvolution to bring out extra detail.Jan 22, 2012

More Calcium-K21 viewsThis image from Jan 17,2012 shows active regions 1401/1402 in Calcium K (393.4 nanometers) as they rotated into view. This region recently threw off a coronal mass ejection (CME) that impacted Earth's magnetic field on Jan 22, 2012 creating auroras at the northern latitudes. To learn more about space weather and its impact to us on Earth, go to our AAG Classroom page and watch the video on space weather. Imaged at f14 using a Stellarvue SV80ED, Lunt B1200 CaK filter and Imaging Source camera.Jan 22, 2012

The Active Sun in Hydrogen Alpha82 viewsThis image was taken through a 40mm Coronado PST of the Sun on 12/27/2011 at 1925UT. The photograph is centered on the hydrogen alpha emission line at 656.28 nanometers (nm) and shows the chromosphere. Active Region 1384 is the dark region near the center of the photograph. A very large prominence is seen erupting along the rim of the Sun on the right.Dec 27, 2011

Messier 1575 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).Dec 26, 2011

The Seven Sisters132 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).Dec 13, 2011

NGC 6559, IC 1274/75, and IC 4685 region in Ha165 viewsThe IC 1274/75, IC 4685 and NGC 6559 complex imaged in Ha are located in the constellation Sagittarius (visible light photo previously posted). Just to the right of NGC 6559 (the brightest emission nebulosity slightly below left of center in the image) in the large HII region IC 4685 is the serpentine structure of the dark nebula Barnard 303. Total exposure 1 ½ hours (TeleVue 85 refractor; SBIG ST 2000 ccd camera @ -13 degrees; Paramount; Baader 35 nm bandwidth Ha filter; 30 x 5 min lights; 35 darks; 41 flats).Nov 25, 2011

Messier 27229 viewsM 27 , aka the dumbbell nebula, in the constellation Vulpecula was discovered by Charles Messier in 1764. M27 is a large cloud of expanding gas, which is the remains of a star that expelled its outer atmosphere near the end of its lifetime. M27 is a bright object that can be seen in binoculars and is a favorite telescopic object in the Spring and early Fall. Total exposure of 1 hr 40 minutes (20 x 5 min lights;30 darks; 66 flats; AP 178 f/9 refractor; Modified Canon 50D; AP 1200 mount; guided exposures)Nov 14, 2011
