The Latest News & Upcoming Events
Famed comet discoverer, and lifetime TVS member, Don Machholz will give a
presentation on Charles Messier, his comets, the missing Messier Objects, the idea
behind the Marathon, and how to run a Messier Marathon. Then, in the course of
about 15 minutes, we will go through the Marathon, object by object, all 110!
In 1965 Don Machholz received his first telescope for his 13th birthday. In 1968-69
he found all of the Messier Objects using a 6-inch Criterion Dynascope. In 1978
he helped to develop the Messier Marathon, and he has conducted more than
50 in the past 39 years. Since 2002 he has been finding all of the Messier objects
from memory, using no charts or setting circles. Don has written a book covering
the Messier Marathon, based on his years of helping to develop and run Messier
Marathons. It was revised and published in 2002 by Cambridge University Press.
Since 1975 he has turned his attention to visual comet hunting.
