Indeed the image has N-S flipped. So north is down,
and east to the left. I'll remind Andrew to check the orientation
in future images... at least for those of us who prefer N-up,
E-left.

Hi Brian,
Is the proper orientation for this picture with the primary galaxy on edge up
and down? Or is the proper orientation with the primary galaxy horizontal
left to right with the three minor galaxies above it?
Thanks!
Rob

Andrew Hayslip has been at work again using DCT for "pretty pictures". His
latest is copied here:

The processing this time is a bit stronger.
