At present there is a comet that is brightening wonderfully and it has finally started to develope a visual tail. It has also become a naked eye object. This is how I saw Comet Lulin with my f/8 6 inch dob at 54X magnification. It has a wonderful soft green glow.

This observation was made just before midnight PST on Feb 20, 2009 (so UT 0800 Feb 21/09)
