Ad Astra Observatory

Some colleges or their libraries subscribe to sites that supply scholarly articles.

I need a copy of the second article on the following list:
http://scholar.google.com/scholar?q=Anastigmatic+catadioptric+telescope&ie=UTF-8&oe=UTF-8&hl=en&btnG=Search

However, all I can get is an abstract. Here are the two links it gives to sites that want $$ to get the article:

http://scholar.google.com/scholar?hl=en&lr=&cluster=7981863036276345589

I’m kind of hoping that there’s some kind of way that I can get this document (perhaps through an academic contact?).

Do you know how to get this actual article?
Do you know how I can find this… cheaply?
