A video of the lecture Martin Byrne gave at Astronomy Ireland last week, a nice overview of the Sligo sites and a little further inland. Best bet is to right click and 'Save as..' then watch it after downloading so you can fast forward past the first 7-8 minutes of an introduction and waffling. It wasnt too easy to hear him on the night but its a lot easier on the video.
