Comet Machholz. date: january 8, 2005 equipment: LX200@f/6.3, LPI.
	Comet 17P/Holmes. This comet was moving away from the sun, so was dimming. Until suddenly it exploded and brighted significantly and was visible with the naked eye and became bigger than the full moon! This was taken with the Z80 and 350D. 11-nov-2007.
	Comet Hartley 103P. 9 October 2010. This comet was quite bright, but with a very low surface brightness, making it difficult to see. It was also moving very fast, as you can see from the long star trails. Equipment: 10" LX200 @ f/6.3, ATIK 16HRC, 15x90seconds. Unguided, frames with guide errors deleted, which explains the holes in the startrails.
