2012_01_17_Sun_SV80ED_CaK_LRdecon_f14.jpg
More Calcium-K862 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.
Jupiter_2015_02_07_6SCT_f25_21AU618.jpg
Jupiter with Io and Europa906 viewsJupiter was at opposition on Feb 6, 2015. In this image Jupiter is framed by its moon Io (L) and Europa (R). Image taken with a Celestron 6"SCT at f25 using an Imaging Source 21AU618 color camera. Stack of approx 2700 images using Registax 5.1, Lucy Richardson deconvolution, and Photoshop 7.0.1.
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars1228 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.
Saturn_2013_05_25_C9_25_21AU618_f25.jpg
The Ringed Planet1057 viewsSaturn is the 6th planet from the Sun at a distance of about 900 million miles. The rings are composed primarily of water ice with particles the size of snowflakes up to house-sized boulders. The rings extend almost 50,000 miles above the planet and average about 60 feet thick (paper thin indeed). To learn more about Saturn, go to our "PLANETS" page. Celestron C9.25 at f25, Imaging Source 21AU618 color camera.
Jupiter_2013_09_29_6SCT_f25_21AU618.jpg
The King of the Planets987 viewsJupiter is visible in the early morning almost directly overhead in late September/early October. Larger than all the other planets combined, its only 1/1000th the mass of the Sun. The bands visible in the atmosphere are due to upwelling compounds whose exact nature is not quite known. Ultraviolet light from the Sun caused the compounds brown, orange and other colors. Imaged taken using a 5" SCT at f25 (~3750mm) using an Imaging Source 21AU618 color camera (1/45 sec exp, 3316 fr cap/2875 stacked /90% qual)
C_2009_P1_Garradd_2012_02_03_71FL_T2i_9min.jpg
The Comet and the Cluster909 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.
2012_05_11_AR1476_Solar_Wedge_90mm_f30_LRdecon_532nm.jpg
Super Sunspot AR17461215 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.
C2013_R1_Lovejoy_2013_12_08_100ED_f7_2_XS_iso800_4min.jpg
Who Needed ISON?854 viewsWhile Comet ISON evaporated while going around the Sun, Comet Lovejoy (C2013 R1) is putting on a show in our morning sky. It is visible low in the NE before sunrise. This is a 4 min exposure through a 100ED refractor at f7.2 with a modified Canon 1000D at ISO 800. The green color is most likely the result of outgassing of primarily diatomic carbon from solar heating. C2013 R1 was discovered on 9/7/2013 and will make its closest approach to the Sun on 12/22.

AR2615737 viewsActive Region 2615 has rotated into view on the Sun on 12 Dec 2016. It measures some 68,000 miles (110,00 km) end to end. Image taken using a Stellarvue 80mm f7 refractor, Daystar sodium Quark at 588.995 nm (D1 line) and Imaging Source 41AU02 camera. Processed using Registax 6.0 Astra Image 3.0SI (for Lucy Richardson deconvolution) and Photoshop V7.0.1. Dec 04, 2016

Saturn_2014_06_26_Takahashi_Mewlon300__8473mm.jpg
Saturn920 viewsSaturn taken with a Takahashi Mewlon 300 Dakin 2.4x barlow and an Imaging Source DBK21AU618 OSC camera from Mayhill NM (2600 stacked images using Registax 5.1).

The Lagoon Nebula922 viewsThe Lagoon Nebula (cMessier 8 or M8, and as NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. The Lagoon Nebula is estimated to be between 4,000-6,000 light years from the Earth. The nebula contains a number of Bok globules (dark, collapsing clouds of proto-stellar material). Imaged using a 100mm F7.2 refractor (112 min) and Hap Griffin modified Canon 1000D DSLR (ISO 800).May 01, 2014

Solar Upheaval853 viewsThe last few weeks have seen the emergence of several large sunspots as solar maximum peaks. Active Region 1967 is wider than the planet Jupiter and its primary dark cores are big enough to swallow Earth many times over. This image was taken in Calcium-K (393.4 nm) from Alamogordo, NM using a 90mm refractor at f20, and Lunt B1200 Cak module and Imaging Source 41AU02 camera. Feb 03, 2014
Sh2-275_2013_12_26_100ED_f7_2_XS_iso800_88min.jpg
A Galactic Rose976 viewsThe Rosette nebula (Sh2-275) is a large molecular cloud in the constellation Monoceros. The nebula is about 4-6 times the size of the full moon in our night sky. The cloud is mostly comprised of hydrogen gas and is illuminated from the group of hot, young stars near its center. The nebula lies some 5200 light years from the Earth. This image was taken from Alamogordo NM using a 100mm f7.2 refractor and a modified Canon 1000D (XS) DSLR.Feb 02, 2014
