Or sometimes it is called the Herring Galaxy? Also, seems that my camera was a bit tilted. Most show the Whale as surfacing - mine seems to be diving. Image with exposure and processing details is at:

Hi Jim

It's trying to get away from the Japanese whaling boats!

Excellent shot!

Hey Jim, that image looks great. I really like your version. The "fin" is really interesting, with lots of mottling and such. Great color too. This one is a winner!
Cheers,
Tyler

I'm herring that for the first time. I've always known it as The Whale.
Fine color in your image, Jim.

Thanks for the comments folks.

Dan, The IAU provides a link to this page:

http://www.seds.org/messier/xtra/supp/d-names.html

Search for "Herring". I personally like "Whale" better. I don't think I'm going to bring up the Herring thing any more. grin
