Hi Tom, shadow watchers, A mirror objective might indeed work. Basically converting the large angular movement of the sun into a much narrower angle at the top and then re-expanding the angles at the bottom. This would be a curved mirror of course, or a set of small mirrors. Approximating i

All: A simpler idea might be to just use a video camera with a fisheye lens. Maybe on top of a flagpole on top of the roof. Edley. Date sent: Thu, 08 Jan 2004 21:35:15 -0800 From: Tom Egan <[EMAIL PROTECTED]> To: sundial@rrz.uni-koeln.de Sub
