Eyepieces

There are times when using a right angle eyepiece during a job is very handy... like when you're trying to look at a very high elevation angle with a transit, or if you have no room to position your head behind an alignment telescope.  So we have a variety of eyepieces to help you out.  Some of these allow you to use a lighting attachment so that you can employ techniques such as autocollimation or reticle projection.
