The Eagle Nebula1868 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.

M16974 viewsMessier 16 (M16) The Eagle Nebula is a conspicuous region of active star formation, situated in Serpens Cauda. The starforming nebula, a giant cloud of interstellar gas and dust, has already created a considerable cluster of young stars. The cluster is also referred to as NGC 6611, the nebula as IC 4703. The distance is 7000 light years.

Super Sunspot AR17461472 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.

Open Clusters M 46, M47, and NGC 2423 in Puppis740 viewsThe open clusters Messier 46, Messier 47, and NGC 2423 are found in the constellation Puppis embedded in a rich field of Milky Way stars. The small planetary nebula NGC 2438 that appears to be in M 46 is actually not associated with the cluster. M 46 was discovered by Messier in 1771. Smyth describes it as a “A noble, but rather loose assemblage of stars†(Smyth and Chambers, A Cycle of Celestial Objects, 2nd Edition, 1881, Oxford) whereas Webb describes it as a “Beautiful circular cloud of small stars†(Webb, Celestial Objects for Common Telescopes, 4th Ed, 1881, Longmans, Green, and Co ). William Herschel observed the small planetary nebula NGC 2438 in 1786. M 47 was also discovered by Messier in 1771 but not intermediately attributed to Messier due to a mathematical mistake in his coordinates. The cluster was described by Smyth as “a very splendid field of of large and small stars†(under the entry 38 H VIII) and Webb as a “Grand broad group, visible to the naked eyeâ€. This wide field picture was taken with a Takahashi FSQ106ED with focal reducer (f/3.6), Canon 60Da DSLR camera (2.32 arcsec/pixel), and an Astro-Physics 1200 mount on 15 March 2015 in Mayhill, NM.. Total exposure of 1 hour (4 x 15 min lights, dithered; 12 darks; 128 bias; 64 flats); Baader/Astro-Physics guider system; Image acquisition with MaxIm DL; Calibration, alignment, integration, and image processing with PixInsight 1.8.3.1123.

Crab Nebula (M1)996 viewsThe Crab Nebula (M1) is a supernova remnant in the constellation of Taurus. In 1731 John Bevis found that M1 corresponded with the bright supernova recorded by Chinese astronomers in 1054 AD as a star bright enough to be seen during the day. The image consists of 47 exposures taken with a Canon 60Da camera, a TPO RC telescope and a Celestron CGEM mount. Exposures were stacked with Nebulosity and processed with PixInsight 1.8.

NGC 2264969 viewsNGC 2264 in the constellation of Monoceros consists of the Cone Nebula and the Christmas Tree Cluster. The Cone Nebula is an H II region and a dark absorption nebula. The Christmas Tree cluster (upside down) is the open cluster above the nebula. The bright star towards the top center (S Mon) represents the center of the trunk while HD 47887 above the cone nebula, represents the top. Not officially part of NGC 2264 is the Fox Fur Nebula, the blue and red furry like area next to S Mon. 200 min total exposure.
