returned to NGC 4039 (Halifax)

I sent the BGO robot back to NGC 4039 and 4038, The Antennae galaxies, to hopefully improve from previous attempts.

galaxies NGC 4038 and 4039 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

I think this is the best result to date... Or very similar to the first (which included a satellite). A challenging target to be sure. Not sure if there's anything I can do to draw out the antennae proper...

Imaged on 22 Dec '17, 27 Jan '18, and 27 Feb '18.
