Trifid Nebula (M20) in Living Color!889 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.
Andromeda Galaxy884 viewsTwo 30-minute exposures stacked of the Andromeda Galaxy (M31) taken with a Takahashi Epsilon 180 f2.8 and a Canon 20Da DSLR.

Sun Spot 1429882 viewsThis is an Ha image of sunspot 1429 on 3-11-12.
NGC 6559, IC 1274/75, and IC 4685 region in Ha878 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).
The Crescent Nebula and surrounding nebulosity877 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.
Super Sunspot AR1746871 viewsSunpots are cooler regions in the photosphere where the magnetic field pops through and cools the surrounding plasma. The latest large sunspot rotated into view on May 5 and is the largest since 2003. Active Region (AR) 1476 spans about 160,000 km (100,000 miles) in this image. Image taken on 5/11/2012 using a 90mm refractor at f30, Lunt solar wedge and 532nm filter with a DMK41AU02 camera. See live images of the Sun on our "PLANETS" page.
Jumpin' Jupiter!870 viewsJupiter is nearing its 2009 opposition - so I thought I'd go out and practice. Shot with the Celestron C9.25/CGE at f/25 (5875mm) with the NexImage/Televue Powermate (2.5x) from the backyard. I shot at 20 fps to get the most amount of images (1800). Stacked with Registax 2.0, Processed with Photoshop 7.0.1.
103P/Comet Hartley 2868 viewsComet Hartley 2, officially designated 103P/Hartley, is a small periodic comet with an orbital period of 6.46 years. It was discovered in 1986. It will be the subject of a flyby by the NASA Deep Impact (EPOXI) spacecraft on November 4, 2010. This image was taken with the C9.25 @ f6.3 with a Canon T2i DSLR (2 ea. 30sec images at ISO 1600) on 10/10/10 at 8:50 PM MT (284:02:50 UT) from Alamogordo NM.
Horse Head Reworked865 viewsThis was taken at Steve's on Nov 2, 2007 this is 7x10 minute images. with TakFS102 and SBig ST2000XCM. I reworked the image to pull out more of the sutle areas.
M15 Globular Cluster in Pegasus862 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).
What a diiference a filter makes!860 viewsHere is the Sun taken on 10/3/11 at 11:15 AM first in White light (left) and Calcium K (right) using a Stellarvue 80ED. The white light image shows a few sunspot groups while the CaK image shows much more detail and areas of increased magnetic activity. AR1302 is on the far right, nearly rotating out of view. The white light image was taken using an Orion glass filter and single snapshot from a Canon T2i. The CaK image was taken with an Imaging Source camera and Lunt B1200 CaK filter.
