is an enlargement of the one above. Notice that the XY Finder has
a low profile to it, therefore back-focus
is kept as low as possible. In the image above, the XY Finder is
attached with a T-Thread coupler. The XY Finder is threaded onto
the guidescope's rear threads, via a threaded coupler. And the ST-237A
is attached to the XY Finder, via a 1.250" eyepiece port. This
piece (1.250" eyepiece port) has T-Threads. So threaded connections
between the XY Finder and the CCD Camera are possible.
