> Here, are some notes from last Friday night. I was observing with the 10-inch, f/4.5 Starfinder from Anderson Mesa, the Lowell dark sky site southeast of Flagstaff.

> This galaxy is among several in the neighborhood of M101. My
sketch presents a 129X view in my 10-inch equatorial Newtonian. NGC
5474 covers a 10'x5' area at the center of the drawing. the core and
main disk appear roughly 5' in diameter. With averted vision a fairly
large spiral arm is seen arcing westward from the disk. A second,
shorter arm reaches to the east-southeast. Neither appears on DSS
images, but this is a loose spiral galaxy and arms should range far
from the core. A 14th magnitude star dimly glows in the foreground
just north of the central disk region. A tight triangular grouping of
11th and 12th magnitude stars is seen about 9' to the northwest. The
10.8 magnitude spiral galaxy is about 26' northwest of 7.1 magnitude
HD 123518. M101 lies beyond the field boundary to the northwest.
> Regarding the spiral arms, has anybody else observed these in NGC 5474?
I have observed NGC 5474 several times with the same 10" Starfinder
and never seen these arms. In my logs it described as coma-like
shaped.
