ICG member Edd Edmondson is a keen amateur astronomer, and last night took the below image of the Whirlpool galaxy from right here in the city of Portsmouth. Whirlpool Galaxy from Portsmouth, Credit Edd EdmondsonWhirlpool Galaxy from Portsmouth, Credit Edd Edmondson The Whirlpool Galaxy (or M51) is a large spiral galaxy (comparable in size to our own Milky Way) which is interacting with its smaller neighbour (to upper right in this image). Both galaxies are about 20 million light years away. This image was taken with a DSLR camara, attached to a 9.25" telescope. It was made by combining a stack of over 100 separate 25s exposures, taking just under an hour of time overall.
