These photos provided by Philip Evans were taken
about 1980 using the 30" guide scope of the MMT on Mt. Hopkins in AZ.
At the instruments Cassegrain focus was a CID camera (NOT A CCD).
Instead of a "Charge Coupled Device" this camera utilized a "Charge Induced
Device". Several different types of cameras were being experimented
with at that time. The CID camera had variable integration
times up to about 30 frames per second. Photo 1 was a 1/4 second
exposure displayed on a 4" green display. Photo 2 was a 1/2 second
exposure. These were then captured on film with a Polaroid Instrument
Camera and were only recently scanned to computer by Philip to display
here. Considering the quality of the solar, lunar and planetary
images being produced by the members of this list it would be an incredible
understatement to say that we have come a long ways in the last 20 years
