M42_M43_2011_10_21_Borg71FL_XS_25min_iso_1600.jpg
Orion nebula complex1148 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.

More Calcium-K852 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_2012_01_03_C6_f25_LR_deconvolution-3it.jpg
Majestic Jupiter850 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.
C_2009_P1_Garradd_2012_02_03_71FL_T2i_9min.jpg
The Comet and the Cluster898 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 Alpha1011 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_2012_02_18_C6_f25.jpg
Mars and Saturn 2012902 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 !
Vega_Betelgeuse_spectra.jpg
A Tale of Two Stars1216 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.
2012_06_05_Venus_Transit_SV80_Cak_decon_-_Copy.jpg
Venus Transit - Calcium K1351 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 M951119 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).
2012_04_27_Moon_6SCT_f20_656nm_-_Copy.jpg
Mare Nectaris/Theophilus crater1163 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 AR17461202 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.
Rho_Ophiuchus_region_2012_05_16_71FL_XS_36min_iso800.jpg
Antares, M4 and the Rho Oph cloud1230 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. Borg 71FL astrograph with a modified Canon XS DSLR 36min exp.
