Boresite for Fastair camera

This is a boresite for focusing fastair cameras.  It is a standin for the camera wherever the camera may be positioned and need to be focuses.

The front bit of the black optical tube has a lens with a crosshair etched in the flat surface there.  The opposite end is an eyepiece thru which you can focus and view the eyepiece.  There is a two piece draw tube focuser which is secured by the two set thumb screws on the right side.

It is all in a a nice Wollensak wood case for storage.
