Mercury is tougher to spot and Mars is just too far left (out of frame). |

PhotographerDan HarrisonLocationnear Fairbanks, AlaskaDateJune 1, 2011 1:13 p.m.EquipmentC-90 spotting scope, image projected onto white paperDescriptionThis is a projection of the Sun with just a tiny sliver eclipsed. Several sun spots also visible. The eclipsed part of the Sun should appear at the "top." |

PhotographerRod PommmierLocationPommier Observatory, Portland, OR, USADate2011-05-08 20:16 PDTEquipmentCelestron Compustar C14 telescope at f/8. SBIG STL 11000M CCD Baader LRGB filters LRGB=184:70:70:70 = 7hrs:04min total exposure.DescriptionThis is the "first light" image with the STL 11000M. Admittedly, M51 and NGC 5195 are not nicely centered, due to my choosing the brightest guide star in the region for my first attempt at self-guiding. The image is still interesting showing the wide field image with colorful field stars and there are at least 40 faint background galaxies visible. The latter include the small blue face-on barred spiral IC 4278 above the bridge and the edge-on spiral IC 4277 above the large, diffuse "E" formed by the tidal spray of stars from NGC 5195. |

PhotographerJohn StetsonLocationFalmouth, MaineDateMay 25, 2011 15h42m and 16h04m UTEquipment90mm h-alpha filter and a webcamDescriptionAn active prominence caught my attention on May 25th. Many prominences this large are quiescent. This active prom was so dymanic that the changes could be noticed in live time at the eyepiece. The set of two images covers a span of twenty minutes. In that time the ejected hydrogen plasma travelled approximately 32,000 kilometers, a rate of 96,000 kilometers per hour. (This rough estimate is based upon: 1. looking at the arc of the sun's limb to determine the size of the sun; 2. the assumption that 110 earths fit across the sun's angular diameter; and 3. the earth's diameter being about 12,800 kilometers.) |

PhotographerBrian McGaffneyLocationBancroft, Ontario CanadaDateApril 04 2011EquipmentCeravolo F9 Astrograph. ME mount. U16M Apogee CCD with Astrodon Filters. Sub guided with 20 minute exp. Remotely accessed to observatory.DescriptionM81 Most Perfect Spiral Galaxy. Taken at the Nutwood Observatory March 2011. Part of the pair M81 and M82. Perhaps the most perfect Spiral Galaxy in the night sky, thanks to close encounters with its neighbour M82 some 600 million years ago. It is a bright galaxy with magnitude of about 6.2. LLRGB, approx 8 hrs. |

PhotographerBrian PoveyLocationPerth West AustraliaDate14th May 2011 05:50EquipmentCanon EOS 50D on tripodDescriptionFor a brief period - Jupiter, Venus and Mars with Mercury just rising. The opportunities were marred by cloud but finally cleared enough to get all four before the sun rose. |
