IC_1805__Heart_11_12_10_7min_TMO_Ha_mono.jpg
Heart Nebula1185 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 Eagle Nebula1549 viewsThe open cluster Messier 16 and the associated nebulosity IC 4703 are found in the constellation Serpens Cauda. The popular name of this object is the Eagle Nebula, and contains the "Pillars of Creation" that was made famous in the image taken by the Hubble Space Telescope. This image was a total of 3.5 hours exposure (21 x 10 min subframes) taken with a modified Canon 40D and a Takahashi Epsilon-180ED.

The Hale 200-inch telescope1241 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 Pinwheel Galaxy1215 viewsMessier 33, aka the Pinwheel Galaxy or Triangulum galaxy, is found in the constellation Triangulum. At magnitude 5.7 it can be seen with the naked eye under dark skies. Its low surface brightness, however, often makes it a challenge even with large amateur telescopes in suburban locations. Image taken with a Takahashi E-180 astrograph and Canon 20Da camera; total exposure 1 hr 40 minutes (20 x 300 sec lights, 30 x 300 sec darks, 64 flats); processed with Images Plus 3.82b and Photoshop CS5.
Helix_Nebula.jpg
Helix Nebula1195 viewsThe Helix Nebula (NGC 7293), aka Helical Nebula or Sunflower Nebula, is a planetary nebula found in the constellation Aquarius. Despite it's designation as a "planetary" nebula, it has no relation to a planet. The term planetary nebula came from the "appearance as a planetary disk" in early telescopes. Planetary nebula are indeed the expelled gaseous remains of aging stars. The image is a total exposure of 1 hr 40 min (20 X 300 sec) taken with a Takahashi E-180 and Canon 20Da DSLR camera.

Narrowband Horsehead region1614 viewsThis is a narrowband image of the Horsehead nebula (B33) region in Orion taken with the Tzec Maun telescope in Mayhill. The "Horsehead" is actually a cold, thick, dark gas that is blocking the light from the bright (emission) nebula behind it. Hydrogen is indicated with red, sulfur is in green (yellow is a combination of hydrogen and sulfur) and Blue is Oxygen. The dats was collected back in January 2011 (3.5 hours worth) and processed by Steve. Thanks Steve !

The Moon1227 viewsThe Moon, our nearest neighbor, provides a wealth of detail even in small telescopes. Indeed, as Garrett Serviss wrote regarding the distance to the moon in his book "Other Worlds" in 1901: "In consequence, of course, of its nearness, the moon is the only member of the planetary (solar) system whose principal features are visible to the naked eye." Image taken with a Astro-Physics 130 mm f/8 refractor and a Canon 20Da DSLR (11 X 1/250 second exposures at ISO 200; aligned and combined in Images Plus).
Jupiter_2012_01_03_C6_f25_LR_deconvolution-3it.jpg
Majestic Jupiter805 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.

The Comet and the Cluster847 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.

Venus Transit - Calcium K1300 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.

Partial Lunar Eclipse 6/4/20121200 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.

Mare Nectaris/Theophilus crater1110 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.
