ASTRO: Comet C/2006 M4 (SWAN) imaged at 0:50 UT Nov 22, 2006.
Image is made from ten 45-second exposures with an SBIG STL-1301E thru a
20-inch F/8.1 RC Cass. Field of view is about 15x15 arc minutes. This comet continues to fade, but it was easy to see visually in a 8-inch F/6 Dob that my friends and I were using. We also had our 6-in Astrophysics refractor on the comet and there were a few other scopes around including a C-9.25, and a JMI 12.5-inch NGT. We finally had a clear night in Binghamton NY with a nice bright Milky Way stretched across the sky until the clouds came in again around 1am local time. It's pretty easy to get low temps on a CCD camera when the air temp is -5C. George N |

Great shot George. Through the large Cassegrain it looks almost as good as
it used to thorugh smaller equipment at it's best time. Stefan "George Normandin" schrieb im Newsbeitrag ...

Stefan, et al: I had a chance to show SWAN to about 30 people last night thru the 20RC. It is much dimmer in just a few days. However, it's still a nice comet! George N |
