Galaxies vary in size, shape, brightness, and contrast. With dark skies, you can begin to resolve the spiral arms and H-II regions of galaxies like M51, M33, and M101. Under moderately light-polluted skies, the dust lanes in galaxies like M104, M64, or the Andromeda Galaxy, M31, are still fairly easy to see. Scores of galaxies with no features at all – dim spirals or boring ellipticals – are also visible with the StarSense Explorer 8”, and some occur in pairs or groups – such as the Leo Triplet containing M65 and M66, the four elliptical companions to the Andromeda Galaxy, or the gigantic Virgo Cluster, a vast region containing dozens of galaxies which can be observed with the StarSense Explorer 8” under dark skies.
