Local Analogues: Comparing a 12-inch Telescope to the Hubble

The College of Wooster Campus Observatory is home to a 12-inch telescope. We aimed to test the limits of the observatory equipment and conditions by targeting nearby galaxies, to determine their morphology based on lower resolution. We suspected that this resolution would be similar to that of the Hubble Space Telescope (HST) for galaxies with a higher redshift. From our images, we hoped to find various variables related to the morphology of the nearby galaxies. These variables included the Concentration, the Gini coefficient, and M20. After two nights of data of the galaxy Andromeda, we began to create an analog between Andromeda and galaxies with a higher redshift but similar masses and Sérsic indices. We found that images from a 12-inch telescope are capable of images similar to those with higher redshift imaged with the Hubble Space Telescope.
