Centering EP

In your list of hardware, on page 10 of the dead-tree version of LEAP, you list for most of the more expensive options an item" "Centering EP". What is that? Erecting Prism? Eye piece?

(I'm sure that it's a foolish question, but I didn't see that item mentioned anywhere in the text.)

Thanks,

Karl

A centering eyepiece is an eyepiece which has some form of cross-hairs in the middle of the field of view, and is usually illuminated. This allows you to exactly center an object in your field of view for alignment.

Here is one like I use:
