Historical observations

NGC/IC Dreyer (1888, 1895, 1908)

This galaxy was discovered by Tempel using the 11-inch refractor at Arcetri. The NGC records it as "pretty bright, pretty large, star 12..13th mag north." Burnham calls it a 12.5 mag spiral galaxy in Cetus, 2.4' x 2.1', "pretty bright, pretty large, round. A fine spiral."
