Sky this Week

Comet C/2004 B1 Linear is around magnitude 12.7 (according to ephemeris) and has a small of 1.5 arc-sec coma. Below image taken with Celestron Nexstar11 telescope, Meade F3.3 focal reducer and Astrovid Stellcam2 video camera at gain 9/14, integrate 128, and medium gamma. Temperature 59°F, clear sky, turbulence fair (5/10), no wind, and transparency was very good. I also created a movie using MS Windows movie maker showing movement of the comet in about 15 minutes (640×480, 15 seconds, 651 Kbytes)
