Comet Lulin (C/2007 N3)
taken on 2/22/2009. The comet is very close to the earth, so the
motion is fast across the star field as shown in these fifteen 20
second frames (total elapsed time is 6 minutes 21 seconds).
Comet Lulin, Feb. 2009 This is the above 15 frames stacked with
the comet position constant to improve the comet image. The resulting
star trails are due to the comet motion.
Comet Holmes 11/02/2007
Photographs taken October 28 -
November 02, 2007 from Lost Maples State Park.
Comet Holmes, 17P had intensified almost 1,000,000 times a few
days before this set was taken. It was still growing in size during this sequence.
These images are scaled to match in size and overlaid. The outer diameter of
the comet increased from about 6' to over 14' during these 5 days.
Comet Schwassmann-Wachmann (73P) was photographed from Bandera on May 12,
