Heart Nebula1341 viewsThe Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The open cluster of stars near the center known as Melotte 15 illuminates the nebula. This is a single 7min exposure thru an FSQ106/Ha filter from Tzec Maun Observatory in Mayhill NM.
Friday Night at the Orion1281 viewsHere's another shot of the Orion nebula using the 6" SCT at f6.3 with an unmodded Canon Rebel XSi (15min total) done on 3/5/10. The nebula is seen as the middle "star" in the sword of Orion. The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. It is located at a distance of 1,344 ± 20 light years. This is an example of a stellar nursery where over 700 new stars are being formed. Cool stuff!
The Hale 200-inch telescope1396 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.
103P/Comet Hartley 21294 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.
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.
The Spider and the Fly1531 viewsIC 417, aka the spider, located in the constellation Auriga is the bright emission nebula in the center of the image. The smaller emission and reflection nebula NGC 1931, aka the fly, is located to the right. In the upper left-hand corner is the emission nebula IC 410. Exposure was a total of 3 hr 10 min (38 X 5 min) with a Takahashi E-180 and modified Canon 40D @ ISO 800 (30 darks, 60 flats). Image aquisition with Images Plus 4.0; Calibration, alignment, and stacking in Images Plus 3.82b.
IC 2177 emission and the van den Bergh 93 reflection nebulosity1736 viewsIC 2177, in the constellation Monoceros, is the large red emission nebula. IC 2177 is often called the Seagull Nebula, embedded in the head of the seagull is van den Bergh 93 (slightly left of center in the image) that actually refers only to the blue reflection nebulosity. Image is a total exposure of 2 hrs 30 mins (30 darks; 60 flats; modified Canon 40D; Takahashi E-180; image aquisition Images Plus 4.0; Calibration, alignment, and stacking in Images Plus 3.82b; Adobe Photoshop CS5)
NGC 6559, IC 1274/75, and IC 4685 region in Ha1320 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 Comet and the Cluster996 viewsComet Garrardd (C/2009 P1) is making a pass through the inner solar system. Early Febuary 3rd it came near Messier 92, a globular cluster in the constellation Hercules. Diatomic carbon (C2) is common in comets giving them a green glow. While its too faint for the naked eye, its an easy telescope target. It will make it closest approach to Earth on 3/5 at 1.27 AU. Captured with a Borg 71FL astrograph and Canon T2i (9 min, ISO 1600) from Alamogordo, NM.
The Active Sun in Hydrogen Alpha1102 viewsThis image was taken through a 40mm Coronado PST of the Sun on 12/27/2011 at 1925UT. The photograph is centered on the hydrogen alpha emission line at 656.28 nanometers (nm) and shows the chromosphere. Active Region 1384 is the dark region near the center of the photograph. A very large prominence is seen erupting along the rim of the Sun on the right.
Mare Nectaris/Theophilus crater1263 viewsThe Sea of Nectar (Mare Nectaris) is a small lunar mare located on the eastern edge of the Moon. Theophilus is the prominent lunar impact crater that lies slightly off center of the image to the left. Theophilus is over 60 miles in diameter and is 14,000 feet deep. The small crater in Nectaris near the top of the image is Rosse and is only 7 miles across. Image taken with a 6" SCT at f20 using a DMK 41AU02 camera through a Lumicom 656 nm filter.
Super Sunspot AR17461300 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.
