NGC 404
From Wikipedia: NGC 404 is a small lenticular galaxy located about 10 million light years away in the
constellation Andromeda. It was discovered by William Herschel in 1784, and is visible through small
telescopes. NGC 404 lies just beyond the Local Group but does not appear gravitationally bound to it. It
is notable for being within 7 arc-minutes of second magnitude star Mirach, making it a difficult target to
observe or photograph and granting it the nickname "Mirach's Ghost".
Mirach, or Beta Andromedae (Beta And, ß And, ß Andromedae) is a prominent star in the constellation of Andromeda. This star has an average apparent visual magnitude of 2.05, which makes it the brightest star in the constellation. Based upon parallax measurements, it is located at a distance of roughly 197 light-years from Earth. It is a red giant with a stellar classification of M0 III. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. It is suspected of being a semiregular variable star whose apparent visual magnitude varies from +2.01 to +2.10. At this stage of the star's evolution, the outer envelope has expanded to around 100 times the size of the Sun. It is radiating 1,995 times the luminosity of the Sun at an effective temperature of 3,842 K.
