The library telescope program places telescopes in local public libraries instead of just schools, allowing greater general access to the scope since they can be put into circulation just as a book.

Where applicable, a local Club member acts as a foster parent to the scope. He or she will periodically clean and adjust the telescope, and act as a local astronomical resource to the library patrons. Additionally, a library member or student from a local school could be engaged as an apprentice astronomer to provide needed care to the scope.

The library telescope lending program uses the Orion StarBlast 4.5-inch Astronomical Telescope along with a zoom eye piece and supportive material. The telescope is easy to use and is robust. There is nothing to assemble. It has a wooden base, not the usual spindly tripod legs. The telescope is of manageable size, but has a relatively large optical tube. This means that the Moon and deep sky objects will show far more detail than one could see with the common "beginners" telescopes. It also has a large field of view that allows the object to stay in the eyepiece longer. This is a quality instrument, reviewed by a number of astronomical publications and found quite worthy.
