Welcome to my Comet Gallery!

The digital images of comets Johnson, 41P, 252P, Lovejoy, Jacques, PanSTARRS (both of them), Garradd, Hartley, Cardinal, Lulin, Boattini, Holmes, Christensen and Wild-2 were taken with Canon digital SLR's through my Tamron 300mm f/2.8 telephoto lens.  The rest are analog images, which were taken with Canon AE-1 and FTb film cameras.
All photos were tracked on my Super Polaris equatorial mount, unless otherwise indicated.

M38 and Comet CARDINAL (C/2008 T2),

April 14, 2009  10:34 pm ET

 

When I imaged the open star cluster M38 in the constellation Auriga, I noticed a faint green fuzzy in the image right beside M38.
While I knew Comet Cardinal was in this general area of the sky, I didn't know it was beside M38 on that particular night. This was a stroke of luck.
Comet Cardinal was very dim; about Magitude 11.
In this image, M38 is near the top.  The comet is the tiny green blur just to the left of M38.  Another open cluster, NGC 1907 appears just below M38.

Comet LINEAR (C/2000 WM1)

November 21-22, 2001
 

This is a digital composite of 8 individual shots I took of Comet C/2000 WM1 (Linear) over an approximate-45-minute period from about 11:30 pm EST November 21 to about 12:15 am November 22, 2001 from north of Burlington, Ontario. This comet was in the constellation Aries at the time. The 8 original shots were taken through my 200 mm lens on Kodak MAX Zoom 800 film, then digitally scanned at 300 dpi, then combined, aligning on the comet's nucleus. The result shows the comet's motion during the total period of about 45 minutes.
