The
Beginning...
My interest in astronomy began when I was 6 years old. My
grandfather, Lathrop F. Berry Sr. proudly showed me a six-inch
reflecting telescope he hand-built in the late 1940's. As
kids, my brother and I could hardly wait to visit Grandpa Berry and
always begged him to get the scope out! He showed us Mars, Jupiter and Saturn and taught us the
basics of stargazing. These exciting outings forty years ago, in Jackson, MI.,
started me on a very rewarding journey which continues today.
The
photo at right was featured in Scientific American magazine. He
designed and built the scope mount, motor drive assembly, optical tube and even
ground his own mirror! Using two pieces of Pyrex glass, he
told us the story of actually walking around a wooden barrel, hour
after hour, using
progressively finer abrasives between the glass discs.
Eventually, the discs took on a curved shape - the bottom
piece became convex and the top concave. The concave piece became
the telescope's mirror. After weeks of grinding, polishing
and testing the curvature, he ended up with an almost perfect
parabolic surface. Shortly after sending the glass away to
Texas to be silvered, he
received a letter; His piece of ground glass was the most perfect parabolic shape they
had ever seen! The company silvered the mirror for free.
