Rasalgethi (Alpha Herculis) -- Double Star in Hercules
The orange star Rasalgethi (Alpha Herculis) rides just above the Serpent Bearer, a fair
distance from the famous Key Stone asterism that defines the constellation Hercules.
This M-class giant has the brightness equal to 760 of our suns. However, what sets this
star system apart is not that it has a massive giant-star at its core, but the stunning
contrast of its two brightest member-stars through the telescope.  The bright orange
and pale blue colors are worthy of a look through any sized telescope that you own.
