M1 is a supernova remnant in Taurus. Charles Messier encountered this delicate emission nebula in the pre-dawn hours of September 12, 1758. His description reads, "Nebula above the southern horn of Taurus, it doesn't contain any star; it is a whitish light, elongated in the shape of a flame of a candle, discovered while observing the comet of 1758." This would become the first of more than 100 "comet-like" objects the Messier would observe and catalog over the next 30 years. M1 is about a degree northwest of magnitude 3.0 Zeta Tauri. A 6.9 magnitude star sits half a degree due east. I've found M1 a challenging object under Midwest suburban skies with a 4.5-inch Newt. In the 10-inch, M1 presents as an elongated S-shape at 129X. Its 8.4 magnitude glow is aligned roughly northwest to southeast and covers a 6'x4' area. Some 40 stars, 9th to 13th magnitude are presented in the sketch at left. The brightest is 9.7 magnitude HD 244988, positioned 10' northeast of M1. |
