Dedicated to Outreach and Education in Practical Astronomy

The Astronomical Unit exists to make reliable astronomical information available to all. I do this through providing free information on this web site and undertaking outreach activities, including Star-tales (astronomy-based story-telling for children and adults), giving Astronomical Talks and running Astronomy Courses in the local community. These outreach activities are run both independently and in association with local astronomical societies, the National Trust, BBC Stargazing Live, local community groups, schools, colleges and adult learning centres.

I also run a companion website, The Binocular Sky, specifically for Astronomy with Binoculars.
