About this image

Geof Lewis recently sent me a number of excellent Messier images which he has been working on during the recent spell of fine weather in the UK.  I was particularly impressed by this image of the interacting galaxies comprising Messier 51, as Geof has brought out very well the various areas of plasma surrounding the galaxies
