back to NGC 4517 (Halifax)

I sent BGO back to NGC 4517. First imaged on 12 Apr '18 but the run then was incomplete.

galaxy NGC 4517 in luminance

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

A slightly better result. And I received all the colour data.
