Comet Holmes (Nov. 7-21, 2007)
Location20kms outside Bangalore, India
DateNov 5th 2007, 2340hrs
EquipmentNikon D50 f/4 at 10 seconds exposure 1600 ASA
DescriptionComet appears as a fuzzy patch along with Perseus constellation
PhotographerPeter W. O'Brien
EquipmentDSI Pro II behind homebuilt 6" f1.8 astrograph
DescriptionThis 3D image was a result of numerous tests of both exposure times and timing between images in order to produce the best overall effect. If you allow your eyes to relax and focus to infinity (as if daydreaming) you should see 3 images of the nucleus, concentrate on the center image until it snaps into place and you should experience the 3D effect. The pay off is the “multiple” structure lines in the outer coma that would perhaps otherwise go unnoticed. Each image is a composite of both 1sec and 8sec data.

DescriptionExposure limited to 30 seconds at ASA 200 due to severe light pollution. I am located directly across the river from lower Manhattan, so it is amazing to get a decent photo of a comet from here.

EquipmentC8 SGT - Nikon D40

DateNovember 3, 9:00 p.m.
EquipmentI took the photo with a 6" f.9 AP Starfire refractor on a Losmandy G-11 mount. I used a Nikon D200 digital camera. I shot ten exposures of 30 seconds each at 400 ISO and then stacked the exposures in Registax and processed in PhotoShop. I increased the blue to brng a better contrast between the outer gas envelope and the nucleus.
DescriptionThe photo shows Comet Holmes Saturday. By by increaesing the blue in PhotoShop, I was able to increase the contrast between the gas envelope and the nucleus.
