摘要：
We present a large field-of-view H (1.65-mu-m) image of NGC 253 and discuss the galaxy's large scale infrared morphology and surface brightness profile. An interative least-squares fit to the surface brightness profile gives the exponential disk and "r1/4" bulge parameters. We confirm the existence of a barred morphology not apparent at optical wavelengths and find that the derived disk scale length at H is slightly less than at B.
