NGC 3184 is a fairly large, bright spiral galaxy with a small nucleus and long sprawling spiral arms. You can find it in the constellation of Ursa Major, where it is well situated for viewing at the present time of year. It's about 25 MLy away so it's relatively close. NGC 3184 is classified (Sbc) and is notable for its high abundance of heavy elements and a supernova that has occurred there recently but is no longer visible. There are a couple of HII regions which have their own NGC numbers and I've identified them on my image. The quasar is mag. 20, z = 2.12. There is actually another superimposed right in front of (or behind!) the nucleus of NGC 3184 but I am sadly unable to positively identify it in my image. It would be very interesting if it turned out to be nearer than NGC 3184 because it has a z of 0.152, whereas NGC 3184 has z of only 0.00191.
38 x 120sec exposures, sigma combined in AstroArt3, produced this one.
For those interested enough to look further, there are several other published instances of quasars identified either in front of nearby galaxies or closely connected to them. 2 of the most convincing are, ngc 7319:

Don't forget to look at all 9 parts!
This site :

lists a whole load of published papers discussing connected quasars and quantized redshifts. Very interesting stuff; there does seem to have been a lot of peer referenced work looking into problems in modern cosmology that has received little or no recognition or credit.
I'm not convinced either way, just find it fascinating.
