Without the need for expensive clock drives and telescopes this is a relatively inexpensive way to bring back some souvenirs of the night sky. It's also a wonderful way of extending what you can see, the film recording much more than you can see with your naked eye. I often take snapshots of the night sky and review them later on with a star atlas looking for future objects to observe. For a beginner this can be a good method for reviewing the shape of the constellations. With all the attention on CCD imaging these days film often gets forgotten, but there still remains a certain charm to the wide fields and simplicity of the method.
Many good books are available on astrophotography, some classics and some new arrivals.
