Aperture is tiny (and expensive, exponentially so). Visible wavelength vs. microwave is a complete overkill in terms of mirror precision (lambda/10..100). Depending on angular resolution you might want to check out a small parabolic sat dish (less wind load on the mount -- which better be not azimuthal -- use a stepper-driven equatorial platform). If you're just going to scan the horizont, it's just one degree of freedom. 2 1/2 if you wiggle a little up and down. Easy enough to improvise for cheap, especially if you do it with a monster dish, which isn't at all like a truss of a lightweight giant scope. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net
