AZ_CA_Space_Shuttle_(3).JPG
Space Shuttle Endeavour1049 viewsTook a tour of the Endeavour exhibit in Los Angeles, CA. For more images of the shuttle, check out our AAG Facebook photo album. Endeavour flew to the Hubble Space Telescope on servicing missions and to the International Space Station and installed the Alpha Magnetic Spectrometer.
Messier_82_Total_exposure_685_minutes.jpg
Messier 82, a starburst galaxy1354 viewsMessier 82, a galaxy in the constellation Ursa Major, was discovered by Johann Elert Bode in 1780. Today we know M82 is a starburst galaxy where a large number of new stars are being born. Large amounts of in-falling gas are excited by the newly formed stars and are responsible for the red Ha emissions Total exposure was 11.4 hours (137 x 5 min lights) taken with a 130 mm f/8 Astro-Physics refractor and SBIG ST 2000xcm CCD camera on an Astro-Physics 1200 mount. Processed in Images Plus 4.5 and Adobe Photoshop CS5

Mare Nectaris/Theophilus crater1412 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.
Annular_Eclipse_Albuquerque_5_20_2012.jpg
Annular Eclipse of the Sun1524 viewsAnnular eclipse of the sun on May 20, 2012 between 7:33:39 – 7:38:05 pm MST (DST in effect) was photographed near Albuquerque, New Mexico in the Cibola National Forest by Sandia peak at an elevation of 6559 feet. The image was taken through Baader solar film with a Nikon D100 DSLR with a Nikon ED 70-300 lens @ 300 mm ( 1/60th second exposure at ISO 200).

Super Sunspot AR17461442 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 cloud1462 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.

Sh2-275_2012_11_12_100ED_XS_iso800_60min.jpg
The Red Rose1401 viewsSh2-275 is also known as the Rosette nebula and is a star forming region in the winter sky. Ionized hydrogen gas gives it a red color. The Rosette is about four times the size of the full Moon and is approximately 5200 light years away and about 130 light years in diameter. Open cluster NGC 2244 is located near the center of the nebula. Taken with an Orion 100ED f/9 telescope and modified Canon 1000D camera, 60 min exposure.

Crater Copernicus1101 viewsCopernicus is a 93 km (57.7 miles) wide crater located in eastern Oceanus Procellarum. It is estimated to be about 800 million years old and is nearly 3.8 km (2.35 miles) deep (over twice as deep as the Grand Canyon!). Image taken using a 6" SCT at f20 using an Imaging Source DMK41AU02 camera.
M97_2013_02_16_120mm_314L+_109min.jpg
The Owl Nebula1203 viewsThe Owl Nebula (Messier 97, or M97) is a planetary nebula in the Big Dipper about 2600 light years away. The nebula formed about 6,000 years ago when a Sun-like star died. The nebula gets its name from the owl-like "eyes". This narrowband image consists Hydrogen alpha, Hydrogen beta and Oxygen emission lines captured through a 120mm f/8.3 refractor and Atik 314L+ camera (109 min total exposure).
2013-04_Yerkes_Observatory_(3).JPG
Yerkes Observatory1112 viewsYerkes Observatory was established in 1897 in Williams Bay, Wisconsin and is considered the birthplace of modern astrophysics. The observatory is operated by the University of Chicago and houses a 40 inch Alvin Clark & Sons refractor telescope. The telescope remains the largest refractor in the world.
LunarEclipse2015.jpg
Lunar Eclipse of Sept 2015790 viewsThe 9/27/15 Lunar Eclipse in Mayhill, New Mexico (9/28/15 02:59:14 UT) taken with an Astro-Physics 178mm f/9 refractor with field flattener and SBIG STF8300c camera on an Astro-Physics 1200 mount; processed in PixInsight 1.8.4.1170.
The_Emission_Reflection_Nebula_NGC_1333_in_Perseus.jpg
The emission-reflection nebula NGC 1333 in Perseus879 viewsNGC 1333 is a blue reflection nebula with associated star forming regions in the molecular cloud/dust region in the constellation Perseus. The star forming regions contain many new stars less than 1 million years old. Red regions of ionized gas energized by these young stars can be seen in the image. Also seen to the left of the blue reflection nebula is the dark nebula Barnard 205. Image is a total of 5 hrs 45 min combined exposure taken on the nights of 23, 27, and 28 October 2014 taken with a SBIG ST2000xcm camera and TeleVue 140 f/5 refractor on an Astro-Physics 1200 mount (23 x 15 min lights @ -20 degrees, dithered; 32 darks; 128 bias; 128 flats). Software: Sky X; Image acquisition with MaxIm DL 6.05; Calibration, registration, and integration in PixInsight; Processing with PixInsight 1.8.3.1123 Ripley (x64) and Adobe Photoshop CC.
