Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars1118 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.

The Veil Nebula1112 viewsNGC 6992, part of the Veil Nebula in Cygnus, is the remains of a large star that exploded in a Type II supernova. The total exposure is 2 hr 25 min (29 x 300 sec lights, 30 x 300 sec darks, 64 flats; Canon 20Da, Takahashi E-180 astrograph, Paramount; Images Plus 3.82B and Adobe Photoshop CS5)

NGC 6559, IC 1274/75, and IC 4685 region in Ha1110 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 nebulosity1102 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 AR17461092 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.
103P_Hartley_2_10_11_10_DSLR_1min.jpg
103P/Comet Hartley 21090 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.
Jupiter_6_21_09.jpg
Jumpin' Jupiter!1085 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.
