shot STF 1682 (Halifax)

Aiming at GSC 05538 00035, I asked the Burke-Gaffney Observatory to shoot the colourful multi-star system Struve 1682. Haas uses intriguing terms when referring to this star in the constellation of Virgo.

aka HR 4877. The B partner, about 3 magnitudes dimmer, is close and to the west-north-west. The C consort is much dimmer, about 6 times the distance, lies to the south-west.

In double stars for small telescopes, Haas describes the primary as "pearly" and the companion as "ghostly" and "ethereal." She quotes Smyth on this one who says they are "topaz yellow" and "lucid purple." SkyTools 3 Pro shows the main stars as deep orange with a classification of K0 while the other two appear white. And B, aka SAO 157549, is a G0 star. It will be interesting to process the captured data in colour...

There's a fuzzy star near the middle-left of the image: that's the core of the elliptical galaxy NGC 4742.
