PhotographerCraig & Tammy TempleLocationHendersonville, TNDateJune 21, 2009Equipment10" Orion Newtonian f/4.7 w/Baader MPCC; Atlas EQ-G w/EQMOD, Guided; Canon 350D (self-modified) w/Astronomik EOS Clip IR filter, 2" Hutech IDAS LPS filter; 31 x 60s @ ISO 1600DescriptionM107 is a loosely packed, magnitude 10.00 globular cluster in the constellation Ophiuchus, about 21,000ly from Earth. It was discovered by Pierre Mechain in 1782 but wasn't added to Messier's list of objects until 1947 |

PhotographerCraig & Tammy TempleLocationHendersonville, TNDateJune 13, 2009Equipment10" Orion Newtonian f/4.7 w/Baader MPCC; Atlas EQ-G w/EQMOD, Guided; Canon 350D (self-modified) w/Astronomik EOS Clip IR filter, 2" Hutech IDAS LPS filter; 9 x 300s @ ISO 400DescriptionAt magnitude 8.00, The Gumball Globular is one of the more faint clusters in Ophiuchus. At one time, it was considered to be a "closely-packed" open cluster rather than a globular. M12 was discovered by Charles Messier on May 30, 1764 and lies approximately 16,000 light-years away from Earth. |

E. Barnard called this region the "Gem of the Milky Way". The large galactic star cluster at the center of the image is M11, the Wild Duck Cluster. It is situated at the northern edge of the star cloud. In the center of the iamge is M11. Larger version here, http://www.hrastro.com/ScutumStarCloudM11/ |

PhotographerHunter WilsonLocationLexington, OhioDateMay 18, 2009EquipmentSBIG ST-4000XCM,Celestron 9.25 Reduced 0.63, Mach1GTO MountDescriptionMessier 3, SBIG ST-4000XCM, 14x600sec,Darks/Flats/Bias Applied,Imager Temp -20C,Celestron 9.25 Reduced 0.63,20% Crop. Messier 3 (also known as M3 or NGC 5272) is a globular cluster in the constellation Canes Venatici. It was discovered by Charles Messier in 1764, and resolved into stars by William Herschel around 1784. This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is located at a distance of about 33,900 light-years away from Earth. Globular cluster M3 is extremely rich in variable stars: By 1978, 212 variables have been found, 186 periods determined, more than in every other globular cluster in our Milky Way galaxy. |

PhotographerHunter WilsonLocationLexington, OhioDateMay 17, 2009EquipmentSBIG ST-4000XCM, Celestron 9.25 reduced 0.63, Astro-Physics Mach1GTO MountDescriptionM56 Globular Cluster in Lyra. SBIG ST-4000XCM, 14x600sec,imager Temp -20C, 30% Crop. Messier 56 (M56, NGC 6779) is located about half-way between Beta Cygni (Albireo) and Gamma Lyrae in an extremely star-rich region. It is one of the less bright Messier globulars, especially lacking the bright core which most globulars have. Nevertheless it is not too difficult to resolve, even at its rather large distance |

PhotographerKenn HopkinsLocationSan DiegoDate04/08/2008EquipmentWilliam Optics Megrez II ED 80mm mounted on a C-11 using a Canon 20D camera. One 5 minute exposure.DescriptionThe largest globular star cluster in our galaxy, Omega Centauri (aka NGC 5139). Omega Cen itself is about 15,000 light-years away and 150 light-years in diameter - the largest of 150 or so known globular star clusters that roam the halo of our galaxy. info taken from http://apod.nasa.gov/apod/ap070419.html |

PhotographerDavid RosenthalLocationMidland Park, NJDate04.27.2009 12:30-3:10amEquipmentModified 400D,8 inch SCT @ f/8 34*240 second ISO 400 exposures. Taken between 12:30 and 3:10 AM EST Atlas EQ-G PHD guided with a 66SD + DSI Pro I Calibrated [30B|30D|30F] and Sigma Clip combined in MaximDL 5 Processed in PSCS3 with GXT and Noel Carboni's ActionsDescriptionM13, also called the `Great globular cluster in Hercules', is one of the most prominent and best known globulars of the Northern celestial hemisphere. It was discovered by Edmond Halley in 1714, who noted that `it shows itself to the naked eye when the sky is serene and the Moon absent.' According to Charles Messier, who cataloged it on June 1, 1764, it is also reported in John Bevis' "English" Celestial Atlas. |

PhotographerCraig & Tammy TempleLocationHendersonville, TNDateApril 16, 2009EquipmentOrion 80ED (f/7.5); Atlas EQ-G w/EQMOD, Guided; Canon 350D (self-modified) with Astronomik IR-block EOS clip filter + 2" Hutech IDAS LPS filter; 40 x 150s @ ISO 1600DescriptionThis globular cluster in Canes Venatici was discovered by Charles Messier in 1764. It is made up of about 500,000 stars. At magnitude 6.2, is is visible to the naked eye in very dark skies. This image is a total of 100 minutes and the temperature was 56° F. The mag. 14.1 galaxy NGC5263 is visible above M3 near the top of the image. |
