Almach – Colorful Double

Object Name: Gamma Andromedae, Almach
Object Type: Double Star
Location: Erbendorf, Bavaria
Date: July 22nd 2007

The double star system Gamma Andromedae – or Almach – as it is also
called, is always worth a visit, when it is riding high in the sky
during long autumn nights. The couple provides a wonderfully rich color
contrast with the main component glowing in a golden-orange and the
smaller component in a blue-green color. The two stars, which are 350
light years away, are seperated by approximately 10 arcseconds and
can thus be easily viewed even with smaller telescopes.

The drawing was made with pencils on white paper, then scanned and
processed digitally in photoshop.

The telescope used was a TAL 6″ f/5 Newtonian on a Vixen GP mount.
