revisited HR 1741 (Halifax)

Sent BGO into Taurus to snap HR 1741 aka STF 680. A double I wanted to view again for its colour.

double-star HR 1741 in luminance

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

On 15 Feb '14 I struggled a bit with the colours. It will be interesting to process the RGB data...


Processed in colour on 4 Dec '17.
