captured NGC 4157 again (Halifax)

I had programmed BGO robot to return to NGC 4157. This was a redo. Back in April, a satellite had drifted through. This is a better image.

NGC 4157 in luminance

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

4157 is a lovely edge-on galaxy. I like the dark lanes in the foreground, north of the bright compact core.
