What to look out, and up, for in May. We start with the constellation of Hercules in our beginner’s and young observer’s guide. Next up is the moon and our round up of the craters and interesting lunar features you can explore with a small telescope. Halley's Comet brings us the peak of the Eta Aquarids on the night of 5th/6th May while Comet LINEAR has the potential to deliver a meteor storm on the night of 23rd/24th May. Mars, Saturn & Jupiter feature in the planetary round up for Northern Hemisphere observers this month and we finish off by galaxy hunting around the Virgo Cluster.
