I just received this message from Publishing at Greenwich, so once again I'm extremely happy with my image being chosen! Just have to wait until 2015 though....
"A commercial calendar manufacturer has approached Royal Museums Greenwich with a proposal to produce a calendar featuring images from Astronomy Photographer of the Year 2013. The first calendar will be for 2015 and we expect it to be on sale in summer 2014.
I am pleased to inform you that your image Receiving the Galactic Beam is one of the images the company has selected to use in the calendar. If you are happy for your image to be featured you will receive a payment of £25 and a copy of the calendar, once it has been printed."
