globular cluster NGC 2419 in luminance

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

Nearby stars; distant stars. A fascinating contrast.

The bright stars to the far west are part of a double star system. HD 60694. The C star is dimmer by 2 or 3 magnitudes and almost due north of A. D is fainter still and due east of A. It is about 5 times the AC split. The B element is extremely tight to A according to SkyTools at ½ an arc-second.
