acquired 14 Ari (Halifax)

The robotic telescope at St Mary's University imaged 14 Arietis (centred on GSC 01761-2074). A multi-star system. This target has been on my View Again list for some time so to spot the B companion.

multi-star 14 Ari in luminance

Luminance only, 4 seconds subexposures, 20 stacked shots. FITS Liberator, Paint.NET, GIMP. North is up; east is left.

I viewed and measured 14 Ari back in Feb 2010 concentrating on the bright wide companion to the west. That's the C star. I did not know at the time it was a triple. B is the much dimmer attendant to the north-north east, slightly less than the AC separation. Very few field stars...
