The Eagle Nebula1710 viewsThe open cluster Messier 16 and the associated nebulosity IC 4703 are found in the constellation Serpens Cauda. The popular name of this object is the Eagle Nebula, and contains the "Pillars of Creation" that was made famous in the image taken by the Hubble Space Telescope. This image was a total of 3.5 hours exposure (21 x 10 min subframes) taken with a modified Canon 40D and a Takahashi Epsilon-180ED.

The IC 1805 region942 views IC 1805 is a bright heart-shaped emission nebula in the constellation Cassiopeia. The open cluster in the center of IC 1805 is Melotte 15 that contains several extremely large stars whose intense radiation ionizes the hydrogen gas in the region. To the lower left of IC 1805 is the bright nebula NGC 896. To the mid-right of IC 1805 is the open cluster NGC 1027. The image encompasses a vast region with the image scale being approximately 3.1 x 2 degrees.
The image was taken with a Canon 60Da DSLR (ISO 800) and a Takahashi FSQ 106ED with focal reducer (f/3.6; focal length = 385 mm) on an Astro-Physics 1200 mount. Image was a total of 6 hours 15 minutes exposure [75 x 300 sec lights (guided with a Takahashi Mewlon 300/SBIG ST-i); 12 darks; 128 bias; 64 flats]. Images selected (SubframeSelector), calibrated (using a “superbias” master), registered, integrated, and processed in PixInsight

NGC 6559 wide field of view893 viewsThis image shows a wider view of my previously posted NGC 6559. This image is a combination of 50 X 300sec exposures with a Canon 60Da connected to an Orion 80mm refractor mounted on a Celestron CGEM. Stacked with Nebulosity 3.0 and processed with PhotoShop CS6

A Tale of Two Stars1313 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.

M46793 viewsMessier 46 (M46, NGC 2437) This open cluster is very rich, with 150 stars of mag 10-13 and probably a total population of over 500. The brightest of these stars are of spectral type A0, and each about 100 times more luminous than the Sun (the brightest is of apparent magnitude 8.7). This indicates an age of about 300 million years. As a special and famous feature which is also obvious in my photograph, a planetary nebula (NGC 2438, also FC 87) appears within the apparent borders of M46. This object appears to lie near the northern fringes of the cluster. However, this nebula is not a true member but is superimposed, or perhaps a passing "guest". The distance of the cluster is 4,600 light years and only about 2,900 light years for the nebula

More Calcium-K941 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.

The Sun in Ha1246 viewsThis is the first light image of the sun taken with my new Lunt 80mm solar scope on Friday 2/24/2012. We used Jim's DMK 41 camera and processed the image in Registax and Photoshop CS5.

Lunar Eclipse1234 viewsImage of the Lunar eclipse on Dec 21, 2010 at 1:17 AM from Mayhill, NM. Although the Moon is in the Earth's full shadow, or umbra, the moon appears to be have a copper-colored glow. This coloration is due to light bent (refraction) or scattered by the Earth's atmosphere onto the Moon. Image is a 6-second exposure with a Canon 40D at ISO 200 through a 130 mm f/9 Astro-Physics refractor on a Paramount.

M33 -Triangulum Galaxy1072 viewsThe Triangulum Galaxy (Messier 33 or NGC 598) is a spiral galaxy approximately 3 million light-years away. It is the third largest galaxy in the Local Group, a group of galaxies that also contains the Milky Way. M33 is about 60,000 light years across and contains 10-40 billion solar masses. Celestron 6" SCT, unguided on GC-5. Stock Canon Rebel XSi, 21 minutes (needs more time-but forgot to charge battery). Taken at Dog Canyon State Park on the 11/22/08 public star party.

IC 410, NGC 1893, and the "Tadpoles"906 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the "Tadpoles", are moving away from the center of the nebula. The image is a total of 9 hours 40 minutes exposure with TeleVue 140 f/5 refractor and SBIG ST2000xcm camera on a Astro-Physics 1200 mount (58 x 10 min lights at –20 degrees C; 20 darks; 64 bias; 64 flats; Images graded in Images Plus 5.0 and calibrated, aligned, integrated, and processed in PixInsight 1.8; final adjustment of star color with Photoshop CC)

M171360 viewsAn image of Messier 17, commonly call the Omega, Horseshoe, or Swan Nebula, in the constellation Sagittarius. There are over 600 stars within this gaseous nebula. The image was taken with a Canon 20Da DSLR at ISO 800 (26 x 5 min light exposures, 35 x 5 min Darks, and 64 lights) and a Takahashi E-180 astrograph. Processed and calibrated using Images Plus 3.80 and Adobe Photoshop CS5.
