Glinos and D. Levy at the Jarnac Observatory, Vail. Martha Farkas (b. 1959) is one of Canada's most experienced amateur astronomers. Farkas prefers traditional visual observing of solar system and deep sky objects using small telescopes. She is an active participant in Ottawa area astronomy events and an enthusiastic promoter of the Adirondack Astronomy Retreat.
