M42_M43_2011_10_21_Borg71FL_XS_25min_iso_1600.jpg
Orion nebula complex1068 viewsNot the greatest picture - but a test of the new Borg 71FL astrograph with the modded Canon XS DSLR. This is a 25 minute exposure at ISO 1600. Come out this winter to see the Orion nebula for yourself at Oliver Lee State Park.

Trifid Nebula (M20) in Living Color!1157 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.

Sagittarius Triple Whammy1763 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,
NGC_1499_small.jpg
NGC 1499 California Nebula1030 viewsThe California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the state of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1,000 light years from Earth. This is a Ha, G, B exposure.

The Hale 200-inch telescope1207 viewsThis summer we took a tour of Mt. Palomar Observatory. The 200-inch (5.08 m) telescope is named after astronomer George Ellery Hale. It was built by Caltech with a $6M grant from the Rockefeller Foundation, using a Pyrex blank manufactured by Corning Glass Works. The telescope (the largest in the world at that time) saw first light January 26, 1949.

The Pinwheel Galaxy1180 viewsMessier 33, aka the Pinwheel Galaxy or Triangulum galaxy, is found in the constellation Triangulum. At magnitude 5.7 it can be seen with the naked eye under dark skies. Its low surface brightness, however, often makes it a challenge even with large amateur telescopes in suburban locations. Image taken with a Takahashi E-180 astrograph and Canon 20Da camera; total exposure 1 hr 40 minutes (20 x 300 sec lights, 30 x 300 sec darks, 64 flats); processed with Images Plus 3.82b and Photoshop CS5.
103P_Hartley_2_10_11_10_DSLR_1min.jpg
103P/Comet Hartley 21110 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.

Narrowband Horsehead region1585 viewsThis is a narrowband image of the Horsehead nebula (B33) region in Orion taken with the Tzec Maun telescope in Mayhill. The "Horsehead" is actually a cold, thick, dark gas that is blocking the light from the bright (emission) nebula behind it. Hydrogen is indicated with red, sulfur is in green (yellow is a combination of hydrogen and sulfur) and Blue is Oxygen. The dats was collected back in January 2011 (3.5 hours worth) and processed by Steve. Thanks Steve !

Milky Way Over Alamogordo1684 viewsThis is a widefield image of the Milky Way taken on 4/29/11 from within the city limits of Alamogordo using a Canon T2i Rebel DSLR on a CGE mount. Visible near the center of the image is Messier 8 (M8, or the Lagoon Nebula), M20 (Trifid Nebula), rich star region M24, open clusters M21, M23 and M25. Globular cluster M22 is visible near the bottom center. To see these objects and more for yourself - come out to our events at Oliver Lee State Park !
2011_10_03_Whitelight_CaK_composite.jpg
What a diiference a filter makes!1067 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.
Jupiter_2012_01_03_C6_f25_LR_deconvolution-3it.jpg
Majestic Jupiter773 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.
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars1135 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.
