Comet Boattini W1 (C/2007 W1)
Comet Boattini W1, taken using G2 10 Aug 2008 10:04:52 - 10:33:09 UTC.
RA 02:39:56.70 Dec 19:57:28.0
7 x 180 sec Luminance bin 1
Comet C/2007 W1 (Boattini), discovered November 28, 2007 by Andrea Boattini (Mt Lemmon Survey)
The finder chart seems to be about 1 or 2 arc min out
an astrometric reduction of the data gives a J2000 RA/Dec of 02:39:50.79 / 19:57:35.3,
wheras my Starry Night gives 02:39:55.1 / 19:57:49. The reference stars are almost spot-on.
This image is a combination of the 7 separate subs, centered on the comet.
