Our clubhouse is in Westford, MA, less than an hour's drive from Boston. Although maintained for our members, any non-member may visit with a member or by other prior arrangement (see the Contact Us page). The clubhouse is on the grounds of MIT's Millstone farmhouse. It is open most clear, moonless Friday and Saturday nights. To check if the clubhouse is open before heading there, call the clubhouse phone line at 978-692-8708.

No traffic in or out of the field is allowed 1/2 hour after sunset without consent of other members present.

Visiting after dark

If you are visiting the clubhouse, please be aware that we have red light protocol after sunset.

  • Do not drive onto the observing field. You can park either in the gravel lot where you enter, or across the street by the tall "garage door" building.
  • Please be courteous with flashlights.
    • Use a small one to keep the stray light low
    • Point it toward the ground only
    • Cover it with several layers of red cellophane or use a red LED light. Red light doesn't affect our adaptation to night vision unless it's too bright or pointed into someone's eyes.


There are many amenities available for our members.

  • Mirror making equipment to help you make your own optics
  • Optical testing equipment to assist with figuring telescope mirrors
  • A machine shop to help you build telescope components
  • Telescopes that you can borrow for the night
  • Observing field with level telescope pads that have etched cardinal points to make set up easier
