Delta Capricorni (Deneb Algeidi, the Ibex's or Goat's tail) is the brightest star in Capricornus at 2.85 visual magnitude. The star marks the asterism's furthest point to the east (quite appropriately, if it's the tail.)

The star is four binocular fields east of alpha Capricorni and a half field to the south: binoculars. Gamma Capricorni is in the same field of view.
