The Moon566 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).
Lagoon Nebula (M8) and Trifid Nebula (M20)68 viewsThe Lagoon Nebula (M8) on the left and Trifid Nebula (M20) on the bottom right are located in the constellation of Sagittarius. M8 is an emission nebula about three times the size of the full moon. The nebula’s brightest region is illuminated by two supper giant stars while the rest of the nebula is illuminated by the open star cluster NGC 6530. M8’s smaller neighbor, M20, is a combination of emission nebula (red) and reflection nebula (blue). The image consist of 4 hours of exposure taken with a Canon 60Da camera and Orion ED80T telescope mounted on a Celestron CGEM mount. Exposures were stacked with Nebulosity 4, processed with PixInsight 1.8, and minor cosmetic touches with Photoshop CS6.
Mars Attacks!520 viewsMars, 11/10/07 ~1139 UT, 6" SCT @ f25, NexImage, 674 frames, Registax 4.0.1. Arcadia Tharsis, Chryse regions. 92.4% illuminated, 13.1 arc sec dia.
NGC7000 American Nebula550 viewsThis was taken with the stock Rebel XT lens at 55mm. It has been croped.
Messier 78 and neighbors120 viewsMessier 78 is a diffuse reflection nebula located in the constellation of Orion. The starlight bounces off the dust particles in the nebula which create the bright reflection areas. The dark area that separates M78 from NGC 2067 consist of obscuring dust that blocks the light from background stars. The image consist of over 10 hours of data (128 x 5min exposures) taken with a Canon 60Da camera, TPO RC telescope on a Celestron CGEM mount. Stacked with nebulosity and processed with Photo Shop CS6.
Venus Transit - Calcium K723 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.
NGC 1499524 viewsNGC 1499, aka the California Nebula, is a diffuse nebula found in the constellation Perseus. The nebula, which is composed primarily of hydrogen gas, was discovered by E. E. Barnard in 1884 using a 6-inch refractor. The image is a total exposure of 3 hours 5 min (37 x 300 sec lights) using a Takahashi E-180 astrograph and a Canon 20Da DSLR at ISO 800 (30 darks, 67 flats). Image processed using Images Plus 3.82b and Adobe Photoshop CS5.
NGC-6946781 viewsImaged at Steves's on 7-7-12. This is 10 - 15min exposures using SBig 2000XCM and a Tak FS102

A Young Open Cluster in a Nebulous Complex 42 viewsThe open cluster NGC 6910 is found in the nebulous emission complex IC 1318, which is located in the constellation Cygnus. As NGC 6910 is near the galactic plane, there is a significant amount of interstellar dust in the area. Indeed, the blue spectroscopic star HIP 100548 (aka SAO 49563) is rendered yellowish white due to the light scattering by the interstellar dust. Estimated distance of the star cluster and nebula is 2,000 to 5,000 light years. Image was taken with a 12.5 inch at f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME in Mayhill, NM on the nights of 4, 5, 21, 25, 29, ant 30 Oct 2016. Total of 14 hr 20 min exposure (43 x 1200 sec lights at -15 degrees C; 18 darks; 128 bias; 128 flats); image acquisition MaxIm DL 6; calibration, registration, integration, and processing in PixInsight Ripley (x64) Mar 03, 2017
NGC 149163 viewsNGC 1491 is an emission nebula found in the constellation of Perseus. It is located over 10,000 light-years from Earth and it forms part of the larger Sharpless 206 nebula. This image consists of over 5 hours of imaging with a Canon 60Da camera, 8” TPO telescope on a Celestron CGE Pro mount. Calibrated, stacked, and processed with PixInsight 1.8Feb 11, 2017
NGC197367 viewsNGC 1973 (Running Man Nebula) is a reflection nebula associated with Orion’s molecular cloud. The nebula is located just .5 degree north of the Great Orion Nebula and 1,500 light years away from Earth. The blue color derives from the interstellar dust reflecting the light from the surrounding young stars. The image consists of 75 x 5min exposures taken with a Canon 60Da and TPO 8” RC telescope mounted on a Celestron CGE Pro mount. Images were stacked with Nebulosity 4 and processed with PixInsight 1.8 Jan 04, 2017
The Milky Way at Sagittarius67 viewsA close-up into the Milky Way galaxy near the constellation of Sagittarius. M8, M20, M17 and many clusters are distinguishable among the dust lanes and dark regions of the Milky Way. Taken from Valley of Fires Recreation Area near Carrizozo, NM on September 24, 2016. The image consists of 20 x 2 minutes exposures utilizing a Canon 60Da at f6.3, 70mm focal length, and ISO1600. Stacked with Nebulosity 4 and processed with PixInsight 1.8.Dec 18, 2016
NGC89172 viewsNGC891 is an unbarred spiral galaxy in the constellation of Andromeda. It is located 30 million light-years from earth and it measures 100 light years across. Astronomers believe NGC891 looks similar to the Milky Way if viewed edge-on. This image consist of 5 hours of exposure with a Canon 60Da camera, 8” TPO RC telescope, and Celestron CGE Pro mount. Processed in PixInsight 1.8. Dec 18, 2016
AR261575 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. Dec 04, 2016
The Crab Nebula in Oxygen[III] and Hydrogen-alpha Emission 85 viewsMessier 1, the Crab Nebula, is a supernova remnant found in the constellation Taurus. M1 was discovered by John Bevis in 1731 (independently discovered by Charles Messier in 1758). Admiral Smyth describes M1 as a “large nebula, pearly white” and of “oval form” in his Cycle of Celestial Objects (2nd edition, page 145). This bi-color image is a total of 17 hrs 20 min exposure using a Takahashi CCA-250 f/5 astrograph and a QSI683wsg CCD camera (Astrodon Gen 2 filters; H-alpha 5 nm; O[III] 3 nm) on a Paramount ME (26 x 1200 sec O[III] lights, 26 x 1200 sec H-alpha lights; 21 darks, 126 bias, and corresponding flats and flat darks). Color assignment H-alpha = red; 15:83 H-alpha:O[III] = green; O[III] = blue; processed in PixInsight 27, 2016
NGC 246 (The Skull Nebula)68 viewsNGC 246 is a small planetary nebula in the constellation of Cetus. The nebula was discovered in 1785 by William Herschel and gets its nickname due to its resemblance to a human skull. NGC246’s central star, is a white dwarf that is entering its final phase of evolution becoming a hot white dwarf. This image was taken on Oct 23, 2016 with an 8" TPO RC telescope, Canon 60Da camera, on a Celestron CGE Pro mount. Stacked with Nebulosity 4 and edited with PixInsight 1.8Oct 30, 2016
