 There 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 Insight.
