Struve 2492 (23-Aquilae) -- Double Star in Aquila
Colorful Double Star in the Eagle
Struve 2492 (23 Aquilae) is a stunning deep yellow and blue-green pair of stars.  It can be
challenging since the secondary star is significantly dimmer than the yellow primary and the
two are relatively close together.  Clean optics and a steady atmosphere helps, as does
high magnification.
