About
I am an amateur astronomer, and a member of the Amateur Astronomers' Association of Princeton (@princetonastro).
I focus on "social astronomy" -- outreach and education about astronomy. I aim to familiarize people with the night sky, especially through naked-eye observations and "constellation walks", but also through telescope viewing.
I own two telescopes (a 70mm refractor and a 150mm reflector). I hope to get involved in astrophotography in the near future.
