340° would have been about right. Position angle is measured counterclockwise from celestial north. Your Yahoo source may have mistakenly measured clockwise, or perhaps meant -20° which is equivalent to +340°.
Quote:I've been imaging this comet for the last month (in its now near gone evening slot) - nice fan tail and yes it is noticibly brighter now
Quote:Tony, have you posted your images anywhere?
I want to do more then just look.

You know you are there when you start thinking in terms of EXIT PUPIL rather than Magnification..
Dan Orion XT8g If your dob isn't broke, fix it anyway. Don't tell me what I want to hear, tell me the truth.
