The Hubble Space Telescope takes images of a very small part of the sky, and the galaxy was too large to fit, so this picture is a mosaic of six Hubble images. The full image, which is not available here, is 91 megapixels! You can get it
here. Many of the images on this page are pieces of the full sized image.
