Default ASTRO: NGC 3193, 3190, 3187, 3185

I processed this before the power supply died and never moved it to this
computer before its demise. Then in all the ruckus forgot about it.
Ran into it cleaning out old files this afternoon.

This is one I did last spring with the 6" f/4. It did go a bit deeper.
F/4 and the higher sensitivity of the ST-7 shows as the faint extended
arms of NGC 3187 were much brighter in the 6" shot. But the 14" gives
far more detail. Next year I'll give it a lot more time

From top to bottom NGC 3193 is the featureless elliptical, NGC 3187 the
faint peculiar barred spiral with the elongated arms, NGC 3190 the
bright peculiar spiral with the tilted dust lane and NGC 3185 a ring
type barred spiral. Looks like 3190 and 3187 may have tidally
interacted some time in the past. But the red shift data would indicate
this is not likely. 3190 is the most distant of the 4 by red shift at
about 90 million light years. The other three are all about the same
distance however with 3187 at 64 million light years, 3193 at 59 million
LY and 3185 at 53 million LY. In any case I've always enjoyed these
four visually in my 10" scope. There are lots of other faint fuzzies in
the background.
