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.
IC_1805__Heart_11_12_10_7min_TMO_Ha_mono.jpg
Heart Nebula1156 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.

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 Comet and the Cluster818 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 Alpha940 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.

Mars and Saturn 2012823 viewsHere is a collage of Mars and Saturn from 2/19/2012. Mars nearest approach to Earth occurs in early March 2012, however it will be almost 60 million miles from Earth (making its disk appear small compared to recent years). Saturn will reach opposition in mid-April 2012, so the disk will be growing larger with each day. Come to our Spring events to see Saturn for yourself !
62_ERATO.jpg
62_Erato 849 views62 Erato is a large and dark, probably carbonaceous main-belt asteroid. It is a member of the Themis asteroid family.Erato is the first asteroid to have been credited with co-discoverers, Oskar Lesser and Wilhelm Forster, who discovered it on September 14, 1860 from the Berlin Observatory. It was their first and only asteroid discovery.
This image is a stack of 25 5 min exposures creating the line showing it's movement.
2012_06_05_Venus_Transit_SV80_Cak_decon_-_Copy.jpg
Venus Transit - Calcium K1269 viewsThe AAG and Oliver Lee State Park hosted a Venus transit event on 6/5/2012 to witness this "once in a lifetime event". This photo was taken using a Stellaruve SV80ED refractor, a Lunt B1200 Calcium-K module and Imaging Source DMK41AU02 camera at the event. Venus and Earth are roughly the same size- so this gives a good approximation of the size of the Sun compared to the Earth. Multiple sunspot regions also speckle the image. The AAG also had white light and hydrrogen-alpha telescopes for the crowd to witness the event.
M95_2012_03_22_6SCT_16IC_32min_SN2012aw.jpg
Supernova in M951033 viewsA Type II supernova recently exploded in M95, a galaxy approximately 33 million light years away. Type II supernova are generated when large massive stars "die" and blow up. Heavier elements such as iron, gold, silver and uranium are created in about a second then scattered into the cosmos. The supernova is still about magnitude 13 so its still pretty dim (given its large distance). Imaged using a 6" SCT at f6.3 using an Atik 16IC camera (32 min exposure).
Moon_2012_06_04_120mm_T2i_partial_lunar_eclipse.JPG
Partial Lunar Eclipse 6/4/20121169 viewsOrbital dynamics of the Earth-Moon system are on display with the latest two pictures on our gallery page. On May 20th the Moon passed between the Sun and the Earth at its furthest point and created an annular solar eclipse. Steve caught a beautiful image from Albuquerque. Two weeks later on the morning of June 4th, the Moon passed partially through the shadow of the Earth creating a partial lunar eclipse. Venus will transit the Sun on the afternoon of June 5th.

Super Sunspot AR17461114 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.

Antares, M4 and the Rho Oph cloud1141 viewsAntares is the bright star at the lower left of the image. It is over 700 times the diameter of our Sun. Globular cluster Messier 4 is seen on the lower right. The Rho Ophiuchus cloud complex is the closest star forming region to our solar system (~430 lght years away). The cloud complex is much larger than can fit in this image. Blue reflection nebula IC 4605 seen about mid-left, and IC4603 seen middle-top are created by interstellar dust.
