IC 452 = NGC 2296, and IC 453. Bigourdan has NGC 2296 = Big 148; this is wrong -- NGC 2296 = Big 147 = IC 452. His relative positions for the two objects and their neighboring stars are precise, and Big 148 = IC 453 is unambiguously a star. Bigourdan's position for IC 453 as published in Observations, Vol. I is correct, though the IC position (from the CR 107, 647, 1891 list) is 8' in error.
Though NGC 2296 looks something like a galaxy on the sky survey plates, it is a small diffuse nebula with an immersed star. It is in a starless patch of sky southeast of Sirius. Clemens and Barvainis, ApJS 68, 257, 1988 have a detection in CO giving a radial velocity of +16.6 km/sec. This confirms the Galactic nature of the object.― IC Notes by Harold Corwin
