Total Lunar eclipse

September 16, 1997

Preparations for the total Lunar eclipse of September 16, 1997 were especially troublesome. We could not get the telescope of Orion Astronomical Society from Maribor, the tool necessary for monitoring the eclipse. After several days the solution came - we borrowed a telescope from the Faculty of education at the University of Maribor.

Four members of Orion Astronomical Society led by Javor Kac drove to Smartno near the town of Slovenska Bistrica, Slovenia from where we covered the eclipse visually and photographically.

Among other projects was our first attempt at a multiple exposure - we made 13 exposures of the Moon on a single frame in 630 second intervals. Between these exposures we also photographed with the telescope - we covered the total umbral eclipse with twenty exposures and the partial umbral phase with further thirty.
