returned to NGC 4216 (Halifax)

Charged BGO with shooting 4216 again. A satellite ran through it 20 May '17. I wanted to revisit again to get more data.

galaxy NGC 4216 and friends in luminance

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

A good result, i.e. no tumbler; but the contrast and detail seems better in the first. The Moon was up...


I noticed that the field is rotated slightly, about a degree or two, from the old photo...
