Zone 188
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.

Notes:
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.
