An ideal destination for the Brownie Stargazer badge.
Demonstrators are Physics and Astronomy postgraduate and undergraduate student volunteers. As an incentive, demonstrators are paid an hourly rate and transportation costs for them to/from Acre Road observatory.
Groups are usually split with half going into the actual observation tower whilst half stay in a newly refurbished classroom and do some activities and then swap.
The demonstrators have always been very patient with enthusiastic Brownies and attempt to answer all questions.
