are dozens of faint galaxies in the background in this image,
dominated by the 11.0 magnitude SA(s)O/a peculiar type distorted
spiral NGC4438. Just to its upper right is the distorting galaxy,
11.7 magnitude NGC4435 - a barred spiral 2.7 arcminutes in length.
The faint blue arms of our dominant galaxy have been tidally
ripped out of the normal location by the barred spiral, which
is considered an interacting pair. This carefully G2V balanced
image shows a nearly white core in NGC4438 along with the faintly
blue tatters of the remaining arms. Inside the core of this object
we can see two brownish parallel dust lanes straddling the core,
along with a smattering of round dust lanes and fragments in
the equatorial plane.
A very strange
object lies in the upper right corner of this field, IC3355.
This 15.2 magnitude Irregular type galaxy is shaped like a orange
slice, and is very blue. The background galaxies are deep yellow
shades because of their extreme distances.
Seeing was bad
on this evening, however quite Gaussian in nature and thus mostly
correctable with the extremely powerful deconvolution in Pix
