Date/Time of photo
November 3, 9:00 p.m.
I 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.
The 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.
