On Friday, Jul. 30, from 7:30 p.m. to 10:00 p.m., the Lyme Land Trust will hold “Mission: The Milky Way,” an astronomy observing session focusing on nebulae and star clusters to be held at an area location to be disclosed. Participants are invited to come anytime during the session, if they park a short way from the site and walk in. Participants who plan to set up equipment are asked to arrive before dark and stay the whole time so as not to disturb others. Reservations are required. Contact Scott Mallory at firstname.lastname@example.org to register and receive full event details.
