Last weekend I shot 2 more videos of the comet Hartley. Although average in appearance, what makes this most interesting is its close path to earth, coming within .2 AU from us by late month/early November. This makes its apparent motion quite visible in the eyepiece if observed for just a few minutes. I shot 40 and 60 minute videos, in which the comet moves 3-4 arc minutes across the sky – the equivalent distance of half way across the face of the Dumbbell nebula. I'll bring those to the meeting next week…
GO TWINS!!
