NGC 7479
Pegasus
Penryn, California
September/October 2007
FS-128G (ag, ST-4)
ST-2000XM LRGB 5 minutes subs.

NGC 7479 is a Seyfert galaxy undergoing starburst activity in the
nucleus and the outer arms (Kohno, 2007 ). Polarization studies of
this galaxy indicate it recently underwent a minor merger and that it
is unique in the radio continuum with arms opening in an opposite
direction to the optical arms (Laine, 2005). It is a type SBb-c
galaxy with a surface brightness of mag. 13.

Extinction due to galactic dust is 0.3847 mag.

Distance is 90 to 100 million light years.

It's distorted enough to support the merger idea. There's nothing
around it to have interacted with it. It's a pretty lonely galaxy. The
Seyfert and starburst classes would also say it ate something. Too bad
we can't get time lapse movies of these guys!

Glen,

one of my favourites too. Not an easy object to get enough signal for the
faint parts as you did.
