PhotographerDaniel JacksonLocationGalilee, IsraelDateNov 17, 2007 at 8:40pmEquipmentThe image is a composite of 6 images taken at three exposure times (15 sec, 30 sec, 60 sec) with a Canon 20D dslr, ISO 800, manual settings, which was mounted at prime focus to a Celestron 105mm "spotter scope" attached to a EQ-5 equatorial drive. The images were combined using Registar v1.07 and finished with Photoshop adjusting the red channel to remove excessive light pollution.DescriptionThe image shows Comet 17P/Holmes passing Alpha Perseus on the evening of November 17, 2007 at 8:40 pm. The nucleus of the comet is clearly visible as is the extended tail. It also shows apparent motion as the leading edge of the scattered light is rounded but the trailing edge is not. |

The image is stacked from 20x155" images at ISO1250. You can see an intersting effect around the bright stars, because we used the F2.8 tele at F5.6. |

PhotographerJoe NewmanLocationEutawville, SCDateNov 20, 2007 4:19am (local)EquipmentCelestron 80ED, Losmandy GM-8 Canon Rebel 350D, Hutech modifiedDescriptionComet Holmes towards the end of the "easy" shooting. Still bright, and fits nicely in prime focus on the 80ED. No moon, but lots of local lights, so used Photoshop CS2 to remove light polution. Just for fun, increased contrast and it makes for a striking, if slightly artificial, shot. This is my first try at astrophotograpy. How lucky can you get to have a comet blow up as your first subject! |

PhotographerAndy KastrupLocationInnsbrook MissouriDate11/17/07 11:20 PMEquipmentOrion SharShoot DSCI II CCD Camera and Pentax 400mm F4 lens.DescriptionThis is a stack of three guided 60s exposures taken in a dense woods. This is the first photo ever with this CCD camera. The moon had just gone down before midnight and clouds cleared to sneak in a few shots before the comet hid behind tree limbs. This particular photo is a good compromise between showing the comet nucleus and surrounding ionized gas glow. |
