M63 Sunflower Galaxy1063 viewsImaged at Steves House. 9 - 15 minute images stacked and processed using PixelInsight.
The Ringed Planet1289 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.
The Owl Nebula1202 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).
Yerkes Observatory1108 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.
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.
The King of the Planets1205 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)
Who Needed ISON?1081 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.
Solar Upheaval1062 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.
Mercury Transit 2016828 viewsThe Mercury transit was well underway when this image was taken at 8:17 AM MT on 5/9/2016 from the AAG outreach event at Imago Dei Academy in Alamogordo, NM. The image was taken using a Stellaruve 80ED refractor with a Lunt B1200 Calcium-K module and Imaging Source 41AU02 camera. The Calcium K-line (393.4 nm) shows supergranulation in the lower chromosphere (~1200 km) along with lighter regions indicating magnetic activity. Sunspot AR2542 along with the small disk of Mercury are also visible.
Massive Filament on the Sun931 viewsA dark filament of magnetism in the sun's southern hemisphere has curled upon itself to form a circle of gargantuan proportions. The circumference of the ring is almost a million kilometers (600,000 miles)! Magnetic filaments are very often unstable, and have a tendency to collapse. Filaments crashing to the surface of the sun can cause of a type of explosion called a Hyder flare. Any flare from this filament could be extra-energetic as it releases the tension stored in its million-km coil. Image taken from Alamogordo, NM on 11/13/15 at 10:14 AM MST (1714 UTC) using a Meade Instruments Coronado 90mm SolarMax II telescope and Imaging Source 41AU02 camera.
White Light Sun842 viewsSunspot AR2403 is almost 200,000 km long and is easily visible in this image taken from Maryland on 8/25/2015 using an Orion ED80T Triplet refractor and a color Atik 414ex camera. The telescope was equipped with a white light filter and the exposure was set to 0.001 sec. Light was further reduced by using a Moon filter in fromt of the camera. Great shot Chuck!
AR2615980 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.
