Corwin's Notes

===== NGC 1977. For the position of this large nebula found by WH, I've taken the Hipparcos position of 42 Ori as representative of the entire object. That will get you there.

Steve's Notes

===== NGC 1977 24" (1/22/15): NGC 1977 is a prominent 20' field of nebulosity involving 42 Ori (V = 4.6 and a challenging 1.2" pair), 45 Ori (V = 5.2) and mag 7.3 HD 37058 on the south side and NGC 1973 (KX Ori) and NGC 1975 (·746) in the northern half. The entire complex is irregularly luminous but locally brightest around these stars and dimmer in the central region. The southern portion is brighter and elongated E-W with an irregular outline. On the southeast side is an extension and the northeast section ends near a 30" unequal pair of stars. See NGC 1973 and NGC 1975 for separate descriptions. 13.1": extensive bright field of nebulosity including NGC 1973 and NGC 1975, very large, elongated ~E-W. Involves several bright stars including 42 Orionis (V = 4.7) and 45 Orionis (V = 5.3). Irregular and detailed with detached segments. Extends north and south beyond 42 Orionis. Located north of M42 and south of the bright cluster NGC 1981.
