Mullard Radio Observatory site near Cambridge. This site is not open to the general public, but I managed a look around with the Cambridge Astronomy Association
This was my 1st visit to Hermonceaux Science Festival in 2009
These are all taken at the Cambridge Institute of Astronomy where the Cambridge Astronomy Association meets monthly.
These are pictures I took at the National Space Centre in Leicester. The planetarium there is very good as well. Worth a visit.
