A colorful star pairing in Pisces

✨Copyright: Drew Evans Drew Evans

 

Last month I found this peculiar and colorful pairing of stars in the constellation of Pisces. Both are variable giant stars in the "Circlet" which represents the head of the constellation. As seen, both vary greatly in spectral class.

 

8 κ Piscium (kappa Piscium) is the blue/white star upper left while 9 Piscium is the yellow star beneath it. There are dozens of faint galaxies beyond these stars, which reside in our Milky Way Galaxy, as seen in the annotated image. Some as faint as magnitude 13. North is up.
