All,
On the "kickstarter.com" website for donating to the fund to restore the
Pluto Astrograph at Lowell Observatory, there is a video of Brian Skiff
talking about the Astrograph used to discover Pluto and of his many
nights using the instrument to take images on large glass photographic
plates until about 1990.
