Observational history

NGC 1255 (DSS)

NGC 1255 was discovered by American astronomer Edward Emerson Barnard on August 30, 1883 with the 6-inch refractor at Vanderbilt University.[3][4] He described it as a "faint nebula, not large, pretty even in light. A faint star close p and slightly south probably involved. Star is s and f the nebula by about 30'".[3] American astronomer Ormond Stone made an independent discovery in 1886 with the 26" refractor at Leander McCormick Observatory, recording "4.1'x2.0', PA 315°".[3][4]

Supernova SN 1980O

Supernova SN 1980O of magnitude 17.0 was detected in NGC 1255 on October 30, 1980.[5][6][1] It was discovered by German astronomer Hans-Emil Schuster with the 1.0-m Schmidt telescope.[5][6] The supernova was classified as type II, and it was located at the following coordinates: RA 03h 13m 27s, Dec -25° 44.50′ (J2000 epoch).[1] By December 30, 1980 supernova had faded by about 4 magnitudes and showed strong P-Cyg-type profiles.[5]
