I am very wary of camera tripods. They don't have the stability of astro tripods.

I created a hot shoe setup using the base of an old flash.

You can get adapters from Ebay to fit Zuikos to Canon Dslrs. This side of the pond, you can get them for about £10 Thu, 19 Nov 2009 09:51:30 GMT D Marcotte http://tech.groups.yahoo.com/group/astrotrac/message/2248 http://tech.groups.yahoo.com/group/astrotrac/message/2248 Perry - Follow on question? Are the Zuiko's Olympus OM lenses? What adapter does one use for a Canon body? I have an M42 or some such thing. Is that it?

Don't have the 28mm, which comes in f/2.8 and f/3.5. It should be a good WA lens, based on the
