Comet Encke image - position?
I've posted a couple of images of Comet Encke fuzzball taken last
night at http://home.freeuk.com/m.gavin/encke.htm I'd like to identify the starfield. Can someone compute Encke's position for 2003 Nov 27 @ 18.33UT? TIA Maurice Gavin @ WPO |

The colour images around tend to show it as blue/green (a sort of OIII colour) Some images I took with an 80A filter seemed quite successful at bringing it out against the sky background. Robin |

Robin Robin - no evidence of a spectrum presumably due to relative faintness of fuzzball. Yes - James Weightman's Canon Rebel image [posted earlier] shows cyan green colour. |
