Object name: NGC0153
NGC 151/153 is a disturbed looking spiral in western Cetus about 160 million light-years from our galaxy by redshift while non-redshift measurements put it 150 million light-years distant, a very good agreement. Using the latter distance I get a size, including the drawn-out arm of about 140,000 light-years. While I call the arm on the left a drawn out arm it ends about 97" of arc from the center of the core but the right-hand edge ends at 98" of arc from the core. So the two sides are pretty equal, just that the eastern side is made up of this one arm and a lot of space with few stars while the western side has lots of stars in several arms and arcs giving the impression it extends further east than west when they are quite equal. The illusion was so strong I had to measure it again just to be sure I didn't make a mistake. Still, the two sides are very different and that begs for a reason.
