Outreach Presentations

The Society undertakes a range of outreach activities at various venues, such as U3A History, Science & Astronomy groups, Rotary clubs, Beaver/Cub/Scout & Rainbow/Brownie/Guide groups, and also local schools. We also utilise the observatory in Hesketh Park that we manage on behalf of Sefton MBC, and this includes public open days and observing sessions, weather permitting. We also hold regular meetings for society members and visitors (always welcome) given by either one of our members or a guest speaker, (see our Programme page). If you would like to hear one of our outreach talks listed below, just complete the form at the bottom of this page.

Rick’s Astro presentations (duration 45-60 min). All these talks can be adapted to meet the requirements of a wide range of audiences.
