M51, the Whirlpool galaxy

M51 or NGC 5194, the Whirlpool galaxy is a wonder to behold at the eyepiece and shows amazing structure in photographic images. It is interacting with the smaller galaxy NGC 5195 which it will possibly merge with. Garry Sedun obtained the frames and I did the processing for this image.
