This the whole setup in action. Right in the middle of the totality. I'm adjusting the centering using the TV monitor.
The base is a home made wood platform that was spiked into the sand. A wedge section supported by threaded rods was aligned perpendicular to the Earth's axis of rotation (an equatorial mount). A 12VDC powered Celestron C-90 mount was attached to that. The mount rotated at a speed matching the sun's (1 rotation/day). A home made bracket attached the Panasonic PV-535 VHS camcorder to the mount. A Sigma VT5 telephoto converter was attached to the front of the camera to get a frame sized image of the sun and eclipse. Finally, a filter made of Roger W. Tuthill's Solar Skreen optical Mylar was put over the lens to capture the entry and exit phases. A small TV was used to view the image being captured. A reticle with circles on it was added to the TV to aid in centering the sun's image.
