NGC_6559___IC_1275_region.jpg
NGC 6559, IC 1274/75, and IC 4685 region in Ha1438 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).
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars1435 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.

Horse Head Reworked1429 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.
Jupiter_6_21_09.jpg
Jumpin' Jupiter!1429 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.

Super Sunspot AR17461427 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.
Crescent_Nebula.jpg
The Crescent Nebula and surrounding nebulosity1426 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.

The Veil Nebula1423 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)

Polaris Star Trails - Second Try1423 viewsThis is a 30 min. shot of polaris. You can see the lights from the steet I shot this over starting to brighten up the bottom of the image.
horse_head.jpg
Horsehead nebula1418 viewsThe Horsehead is a dark globule of dust and non-luminous gas, obscuring the light coming from behind, especially the moderately bright nebula IC 434. It is the most remarkable feature of an interesting region of diffuse nebulae, which belongs to a huge cloud of gas and dust situated 1,600 light years away in the direction of constellation Orion. The bright reflection nebula in the lower left is NGC 2023.
