Holmes - Moon Comparison27 viewsHere's a montage of my images showing Comet 17P/Holmes' size relative to the Moon starting approximately one day after it's outburst (10/25/07, 5:30 AM EST) to 25 days after. Note the difference in exposure times as the comet expanded (0.5 seconds to 5 minutes). I tried to pick images with similar surface brightness as best I could. All images are at the same image scale- prime focus in a 10" f/5.6 Newtonian reflector.

Saturn and Titan26 viewsThe seeing is really good tonight so I took a picture of Saturn. This is from a 5 minute video using a Meade LPI and my 114 mm Celestron F8 FirstScope with a 5X barlow. Assuming the camera chip is equivalent to a 6 mm eyepiece, the equivalent magnification = 760 X..... Not too many nights around here that one can use that kind of power!
