Mendel Observatory

Wednesdays: Open to the Public

With the support of volunteers from the North Shore Amateur Astronomy Club, the observatory hosts public stargazing every Wednesday night, weather permitting, starting at dusk or 7 p.m. -whichever is later.

When special astronomical events of interest occur, such as a total lunar eclipse, the observatory often holds special viewing times.

We ask that the telescope not be operated in temperatures colder than 32˚F until further notice.

Thursdays: Open to Merrimack 

On April 5 we officially launched our student-led Star Party at the Observatory. The event takes place every Thursday at 8 p.m., weather permitting. Come and join us as we observe planets, double stars, the moon and deep space objects, such as galaxies and nebulas. The entire Merrimack community - students, faculty and staff - are welcome.
