Number 27 in the Herschel 400 list, NGC 654. NGC 654 is a reasonably small open cluster in Casseopia, surrounding the bright yellow giant star, SAO 11950. I am unsure if the giant star is an actual member of the cluster or just a foreground object, but I suspect the latter. The other stars in the cluster are moderately faint.
