Hubble M31 PHAT Mosaic in Ground-based Image of M31
The Hubble Space Telescope M31 PHAT mosaic image is shown in context with a ground-based image of galaxy M31. The background image, taken by Robert Gendler, was made by compositing M31 data from a 12.5-inch Ritchey-Chretien telescope with M31 data from the Digitized Sky Survey.
