Quote from Dreyer's New General Catalog (NGC):
"Pretty bright, 2 arc minutes long, little extended."
NGC 2146 is a relatively nearby peculiar Barred Spiral Galaxy in the Constellation of Camelopardalis. It is a nearly edge-on disturbed starburst galaxy (i.e. enhanced star-forming activity). It has a peculiar large nuclear bulge with many irregular absorption markings and two main smooth spiral arms, one with a dark lane. The extremely broad spiral arms appear asymmetric, and probably lie in different planes. Thus NGC 2146 could have a very warped disk, twisted through an angle of about 45 degrees.
This galaxy is associated with radio source 4C 78.06 and several infrared sources, plus its optical spectrum shows bright hydrogen alpha lines. Hutchings et al. (1990) suggested that NGC 2146 is in the final stages of a collision and merger and found no evidence of an active nucleus. It may be interacting with NGC 2146A which lies 18 arc minutes away.
