Rick,
this galaxy is similar to NGC 2841 as it also needs good detail to show any
detail at all. You did much better than I was able to a few years back:

This one reminds me of a hypnotist's spiral.
NGC 488 is a tightly wound spiral (SA(r)b) located in Pisces about 90
million light years away by red shift measurement or 95 by Tully-Fisher
analysis of its rotation rate. Being nearly face on that must be a
tough measurement. It seems to be made up of mostly arm segments that go
only about half way around then fuzz out. Still I seem to see but one
continuous spiral if I follow the fuzz between segments. This is easier
to do if the image is enlarged some. Unfortunately, seeing wasn't all
that good so I had to limit my enlargement to only 33% or 0.75" per pixel.
The field isn't covered by the Sloan Digital Sky Survey so few of the
galaxies are cataloged. I've labeled all that are and include distance
data for those few that had it. One galaxy cluster (GC) is annotated in
the image. The line points to its center. NED shows it containing 17
galaxies but gives no size. It shows it as about 3 billion light years
distant. Most members in my image appear to be east of the center.
There is one "bright" asteroid of 19th magnitude and several of 20th.
Due to the bad seeing and low transparency as well as their rapid motion
they are far fainter than normal. I didn't label the 20th magnitude
ones. The gap in the trail is due a meridian flip 20 minutes into the
image. On cold winter nights like this one (outside temperature was
below -30C) I slew at only 30% normal speed. That means a couple minute
delay in the flip. The gap is longer than this as I apparently allowed
7 minutes for the flip instead of the 3 I usually program in.

Correct domain name is arvig and it is net not com. Prefix is correct.
