PhotographerRod PommierLocationPommier Observatory, Portland, ORDate2009-07-29T15:34:23' /UT of midpoint of exposureEquipmentCompustar C14 Schmidt-Cassegrain @ f/7. Canon EOS 20D Exposure: 240 x 30 seconds = 2 hours at ISO 1600DescriptionM27 lies about 1200 light-years from Earth and has a diameter of about 2.4 light-years. It's expansion rate indicates that the red giant that spawned it erupted between 3000 and 4000 years ago. The white dwarf remanant of the red giant lies at the center of the nebula. This image shows some of the subtle detail inside the nebula. Sub-frames were 30-second unguided exposures calibrated with dark, flat and bias frames. |

PhotographerCraig & Tammy TempleLocationHendersonville, TNDateJanuary 4, 5, 10 & 13, 2010EquipmentOrion 80ED at f/7.5; Astro Tech AT2FF zero-power field flattener; Canon Digital Rebel T1i, Hap Griffin Baader modified; Hutech IDAS LPS-V2-FF EOS Clip (RGB); Astronomik 6nm H-Alpha EOS Clip (Ha)DescriptionProbably the most famous and easily recognized deep-space object, Barnard 33, a dark nebula commonly known as The Horsehead, is situated in the middle of the constellation Orion. It gracefully stands out in front of emission nebula IC 434. Also visible in this image, is Alnitak, the very bright left-most star in Orion's belt. Below Alnitak is the Flame Nebula, NGC 2024, an emission nebula energized by Alnitak. To the left of The Flame is reflection nebula IC432. Above IC432 is reflection nebula IC431. To the right of the Flame, is reflection nebula, NGC 2023. The reflection nebula below NGC 2023 is IC435. |

PhotographerNiels V. ChristensenLocationCopenhagen DenmarkDate5->7. March-2010EquipmentMeade LX200ACF 16" telescope mounted on wedge, SBIG ST-8XME camera and Astronomik LRGB filters used.DescriptionM51 exposure times are LUM=39 5min. plus R,G,B=10,10,10 5min. subs. taken with a telescope focal lenght~2m., Optec NextGEN Wide Field 0.5X reducer used. Due to light polution from the city of Copenhagen additionally a IDAS LPS filter was used. CCDStack and Adobe Photoshop CS4 applied for picture processing. Dark, flat and bias frames used for calibration of the raw LRGB frames. Picture size is 66% of the original size. |
