Over the years I have come across a wide range of online resources which I have found useful. Many of the tools and utilities available to the amateur astronomer are free of charge and have often been produced by amateur astronomers. You will notice that the vast majority of links are based in the UK. Apologies to any overseas visitors. You can enjoy the better weather so its only fair your UK counterparts enjoy better links!
Rather than attempting to provide a summary of what each link is I prefer to let the website the link points to do that for me. To give you a rough idea of what to expect the navigation menu on the left has been categorised to make finding appropriate links a little easier.
If you know of a website that you feel would be useful to others please let me know at firstname.lastname@example.org and I will do my best to include it. I am more than happy for anyone to add links to my website from their own.
