Welcome!
The Amateur Telescope Makers of Boston, Inc. (ATMoB) is an astronomy club devoted to telescope making, observing, and studying the heavens. The ATMoB was founded in 1934 with the cooperation of Dr. Harlow Shapley at Harvard College Observatory.

We meet formally every month (except August) to hear a speaker, to discuss club activities, and to socialize. Membership is open to all those interested in pursuing astronomy as a hobby.  For additional details...
Next Club Meeting
Meetings are held the second Thursday of each month, except August.

Meetings are held in Phillips Auditorium, Harvard-Smithsonian Center for Astrophysics and are open to the public.
