Instructor: David Kiefer holds various Masters degrees, including a M.S. in astronomy from the Center for Astrophysics and Supercomputing in Melbourne, Australia. He has taught physics and astronomy at colleges in New York and New Jersey, and is presently a lecturer at Brooklyn College. A member of the AAA, Mr. Kiefer observes at Floyd Bennett Field in Brooklyn and at upstate sites. He also teaches AAA Classes and is in the Class Coordination Committee.
Evergreen Messier Half-Marathon 2021
Friday, March 5
5:30 – 11:59 p.m. EST
Location: Evergreen Cemetery, 1629 Bushwick Ave, Brooklyn, NY 11207
A fun night of observing and photographing Messier deep sky objects.
Lecture: Dr. Kelle Cruz and Tim Pickering Present, “Open Source Astrophotography”
Tuesday, March 9
7:00 – 8:30 p.m. EST
About the Speaker: Tim was an active amateur astronomer as a teenager, who received his first telescope when he was 11, and built a 10” dobsonian telescope from scratch when he was 16. Tim decided to pursue astronomy as a career when an advisor told him that if he went to graduate school in astronomy, he would get to use the largest telescopes in the world— and get paid to do it. He was right, and in the past 20 years Tim has made stops at the MMT Observatory, the Southern African Large Telescope, and the Space Telescope Science Institute.
Monday, March 15
7:30 – 8:00 p.m. EST
