I was taking some photos of the moon the other night and was surprised at one of them:
On zooming in to full size:
And in another photo about 6 minutes earlier, there was another lunar explorer (too blurred to show here). I didn't realise that the airway that goes across East Anglia (TRENT to CLACTON?) was so busy.
In this year's Wildlife Photographer of the Year awards, the winner of the 'One Earth' section award was an almost identical photo to yours, Ian. It was entered by a Hungarian photographer who had been trying out his new 500mm lens and didn't realise he'd caught that shot until he uploaded the images on to his PC.
Here's a small version of it along with some of the other fantastic entries, but if you are out shopping in the sales, slip into a bookshop and see the full size version in the WPOTY portfolio 17. I get it every year as my christmas present so it's spooky that your photo should pop up at the same time!
