A good place to get non-laser collimation tools and an informative book.
http://www.shop-cabinets.com/collimation/tools.html I've only ever done it once at a star-party, as a demonstration. Usually
at home while working on a scope. But it could easily be done anywhere.
The nice thing about an artificial star is that the scope need not be tracking to observe it- a nice feature for most Dobs. An electrical pin-hole-type star could be used at a star-party after dark, set up some distance away. With a decent battery pack, could be left on all night.

Do you do this on location prior to night fall?
