-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Scott Campbell and I both live in Texas, and in an unlikely physical arrangement. I'm 183km to the north of him and less than 100 meters west of his site. Is there any use for this arrangement for optical observation? I know for some types of radio work it'd be useful, as a very large synthetic aperture, but I don't know an inexpensive way to do that sort of thing at the moment.
