Sculptor_Galaxy.jpg
Sculptor Galaxy611 viewsThe Great Sculptor Galaxy (NGC 253), aka the Silver Coin, in the constellation Sculptor was discovered in 1783 by Caroline Herschel. The galaxy is at a distance of 9.8 million light years away from us. Research on NGC 253 indicates that it is a starburst galaxy, which means that it has recently hosted massive and rapid burts of star formation. The image is a total of 1 hr 50 min (22 X 300 seconds) exposure with a Takahashi E-180 astrograph and Canon 20Da DSLR camera.
Eagel_Nebula.jpg
The Eagle nebula731 viewsThe Eagle nebula (M16) found in the constellation of Serpens as seen on May 4 2013. This a compilation of 8 180sec photos taken with an unmodified Canon 60D ISO3200 attached to a Meade 8"SCT with focal reducer and Baader UHC-S filter on a Celestron CG-5 stacked with Nebulosity3 and processed with Photo Shop Elements.
ASIC410.jpg
IC 410 and the Tadpoles in Ha103 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the “Tadpoles”, are moving away from the center of the nebula. The image is a Ha image, which shows the extent of the hydrogen emission in the region. The image was taken with a Takahashi CCA-250 astrograph and the QSI683wsg camera (SBIG ST-i guider) on a Paramount ME. The image is a total of 8 hours exposure (24 x 20 min lights @ -20 degrees C, dithered; 21 darks; 126 bias; 128 flats), acquired with MaxIm DL 6.07, and processed with PixInsight 1.8.3.1123 Ripley (x64). Ha filter was an 5nm bandwidth 31 mm Astrodon Gen 2 filter.

The Bubble Nebula230 viewsThe bubble nebula in the constellation Cassiopeia was taken with an Astro-Physics 130 f/8 refractor and an SBIG ST2000xcm camera (cooled to –20o C) on an Astro-Physics 1200 mount. The total exposure time was 10 hrs 5 min (121 x 5 min lights; 33 darks; 64 flats) and the images calibrated, registered, combined and processed in PixInsight 1.8 with final adjustments in Images Plus 5.0 and Adobe Photoshop CC.

Barred Spiral Galaxy in Leo77 viewsNGC 2903 is a intermediate weak-barred spiral galaxy (SABbc) found in the constellation Leo. Discovered by W. Herschel in 1784, NGC 2903 is approximately 20 to 30 million light years away. Image was taken with a 12.5” f/9 RCOS telescope and a SBIG STF8300c camera with an OAG (ST-i) on a Paramount ME. Image a total of 15 hr 20 min of combined exposures taken on 12, 13 Jan and 8,9,12 Feb 2016 in Mayhill, NM (46 x 1200 sec lights @ -15 degrees C, dithered; 30 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.4.1195.
SoapBubbleHaCropfinal.jpg
The Celestial Bubble in Cygnus91 viewsThe Soap Bubble Nebula, or PN G755.5+1.7 is likely a faint planetary nebula found in the constellation Cygnus. The faint nebula was discovered relatively recently in 2008 on photographs of the Cygnus region. A cropped hydrogen-alpha image attached. Image was a total of 5 hr 40 min taken with a Takahashi CCA-250 f/5 astrograph with a QSI683wsg camera (Astrodon Gen2 Ha filter 5 nm) on a Paramount on the nights of 2, 4 October 2016 in Mayhill, NM (17 x 1200 sec H-alpha lights @ -20 degrees; 23 darks; 128 flats; 126 bias; processed in PixInsight 1.8.4.1195).
Mercury_Transit_0818MT_SV80ED_CaK_41AU02.jpg
Mercury Transit 201669 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.
IC_410_and_NGC_1893.jpg
IC 410, NGC 1893, and the "Tadpoles"249 viewsThe emission nebula IC 410 and the embedded open star cluster NGC 1893 are found in the constellation Auriga. The emission of IC 410, which is about 12,000 light-years away, is powered by the young hot stars in NGC 1893. The gas streamers just to the right and above center, often called the "Tadpoles", are moving away from the center of the nebula. The image is a total of 9 hours 40 minutes exposure with TeleVue 140 f/5 refractor and SBIG ST2000xcm camera on a Astro-Physics 1200 mount (58 x 10 min lights at –20 degrees C; 20 darks; 64 bias; 64 flats; Images graded in Images Plus 5.0 and calibrated, aligned, integrated, and processed in PixInsight 1.8; final adjustment of star color with Photoshop CC)

NGC6910_L.jpg
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 1.8.4.1195 Ripley (x64) Mar 03, 2017

Running_man_ABE_ps.jpg
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

M1finalJPEG.jpg
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 1.8.4.1195.Nov 27, 2016
NGC_246.jpg
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
