Notes: It was discovered by W. Herschel in 1783. It lies 95,000 light years from NGC 3169.
Observations:
C8 at 104x. It is a bright oval haze. It takes high power well, but does not give up any visual details. Its axis runs E-W. NGC 3169 is only 5 min E. Model (where the Sun is a baseball):
Its diameter would be 27 million miles.

This is a Seyfert galaxy and is interacting with NGC 3166. This galaxy produced supernova 1984E and 2003cg (type Ia).
Observations:
C8 at 104x. Oriented NE to SW, it has a stellar center and uneven light. A very faint star lies to the E, as well as the galaxy NGC 3166 to the W. Model (where the Sun is a baseball):
