Angle Finder

What is a right angle finder and how we use it?
I found this angle finder on ebay … I found that fits the type of camera you have … I have no idea what they do not really … Can you explain what this odes? Thanks, Scott Here it is: http://cgi.ebay.com/Nikon-DR-4-Right-Angle-Finder-for-F5-F4s- F100-N90-NEW_W0QQitemZ160160417444QQihZ006QQcategoryZ29968QQssPageNameZWDVWQQrdZ1QQcmdZViewItem I do not buy it … I saw it and was curious as to what he does.
Basically, it attaches to the viewfinder eye piece allows you to frame and focus down instead of looking through the eyepiece. It is a very useful piece of equipment that you use a tripod much. If you do not use a tripod much, probably will not have much use for it.
