Here are some other suggestions: This site shows one made for sketching but it would work for looking at a star chart(s): http://www.perezmedia.net/beltofvenus/archives/000331.html This is an expensive alternative but a LED Grill Light that clips should be able to be modified: http://www.target.com/gp/search/187-9735127-4599137?field-keyword Target's price is $49.99 while Home and Garden at Amazom.com has the same light for $19.75 and here is that link: http://www.amazon.com/Maverick-Indust-GL-05-Basic-Grill/dp/B000TKRQEE/ ref=sr_1_6?ie=UTF8&s=home-garden&qid=1237649312&sr=8-6 Anyway, they are some alternatives. You might consider a book light with a clamp and modify that as well. http://books.barnesandnoble.com/search/results.aspx?WRD=book+lights Good luck with what you decide. Jay
