Tamron Article

Tamron, a company that manufactures a great line of lenses asked me to work with them on an article on astrophotography because of the newest comet, Comet Holmes. Here is the url:

Comet Holmes

An interesting new comet that has become very bright. This shot is a stack of nine exposures with a Canon 20D and a Tamron 180mm F/2.5 lens at 400 ISO and three minute subs. I had the assistance of my brother in law Ted and my friend, Sheldon.
