M101 - The Pinwheel Galaxy is one of the largest disk galaxies known. It has an estimated distance of about 24 million light years and is roughly 170,000 light years in diameter with an estimated mass of about 30 billion suns. This is a wide-field image using an 80mm refracting telescope. I opted for a wider field to include many of M101's neighboring galaxies of which half a dozen or so can bee seen in this image.
