NGC 488 You are getting sleepy

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.

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:

Actually you had quite a bit of detail. Just needed a run through the
high pass filter to pull it out.

I've been told this one is really a time vortex. I did a bit more
enhancing of the image, this time using Hoagland's hyperdimensional
physics based processing tools. Great for pulling out detail normally
seen only by averted imagination. Amazing what these tools can see.

Oops, forgot the "reprocessed" image.

Well, I guess these vortexes can get really nasty if you get near them. I am
glad it is in NGC 488 and not in my bathroom.

I don't know if Dr. Who plays in Germany. If not the image won't make
much sense. Dr. Who is a campy English SiFi series that has run for
decades (1963 I think, with a couple decade gap, to the present). It
uses very cheap, cheesy special effects as in my "doctored" image. The
Doctor (he has no name I'm aware of) is a time lord who travels through
time and space in a "TARDIS" (Time And Relative Dimensions In Space).
Which is multidimensional. On the outside it appears to be a 50's era
English police call box just big enough for one policeman to fit into.
But it is as big inside as as a sound stage allows. That's his TARDIS
in the image or as best as I could do.
