Pi Aquilae (Struve 2583) -- Double Star in Aquila
Splitting Pi Aquilae
Pi Aquilae is a pretty double star about a degree northeast of the star Tarazed (Gamma
Aquilae) in the constellation of the Eagle.  To cleanly split this tight double it requires a
stable atmosphere, high power and at least a three-inch aperture telescope.  In my
2.4-inch refractor I can make out an elongation in Pi Aquilae but cannot split it.  With my
6.1-inch refractor at 312x magnification (used in the drawing), the separation of 1.4
arcseconds was not difficult.  I see both stars as white.
