Galaxy NGC 895 and Supernova 2003 id
Color image taken with an ST-9E CCD camera thru Kopernik's 20 inch F/8.1 telescope. Image taken under poor seeing conditions at 4:45 UT on September 21, 2003. The field of view is 8x6 arc minutes with North at the top.

Spiral Galaxy NGC 895 ( and NGC 894 ):

This 11.9 magnitude galaxy is in the constellation of Cetus. IIt is a face-on spiral galaxy with a very small, bright nucleus, 2 main knotty arms. Low-surface-brightness spiral arm fragments exist over the outer area of the disk on the outside of the principal arms. Unfortunately, because of the poor seeing conditions, the Kopernik image above does not show the structure of the arms.

NGC 894 is not a separate object, but rather it's the northern arm of this galaxy.

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 895 and SN 2003 id is 120 million light years, with a galaxy diameter of about 126,000 light years.
