There are loads of resources available to anyone interested in astronomy. Here are some of the ones I find the most useful.
Astronomy Now magazine. A monthly look at what’s new in astronomy, including details notes on what to look for in the night sky and how to find it. There’s also BBC Sky at Night magazine, but I prefer Astronomy Now. (Full disclosure: I write feature articles for Astronomy Now from time to time.) You can find the magazine in most large newsagents or subscribe online.
The Evening Sky Map. A monthly guide to the night sky and a list of key things to look out for. The best bit, though, is that it breaks down that month’s observing targets by things that can be seen with the naked eye, with binoculars and with a telescope. And it’s absolutely free. Available online here.
Stellarium. Free planetarium software that allows you to see how the night sky appeared, appears or will appear anywhere on Earth at any point in time. Great for checking out what you’ll be able to see on any given night or for figuring out what something is that you can already see. Also useful for archaeoastronomy, as you can see easily when and where different stars would have appeared in ancient times. Download it here.
First Light Optics. My first port of call for all things astronomy. They sell a great range of telescopes and accessories and are always extremely helpful with advice on what would best suit your needs. I’ve ordered various things from them over the years and have never had a problem with anything they’ve sent me. Find them online.
