Description

IC 2391, also known as the Omicron Velorum Cluster or Caldwell 85, is an open cluster in the constellation Vela.

The cluster is about 500 light-years away from Earth and can be seen with the naked eye.
It contains about 30 stars with a total visual magnitude of 2.5, spread out along 50 arcminutes.

Omicron Velorum (ο Vel) is the brightest member of this open cluster. It is a blue-white B-type subgiant with a mean apparent magnitude of +3.60, approximately 495 light years from Earth. 
The brightest star in this image is Delta Velorum (δ Velorum, abbreviated δ Vel), a triple star system, near the border with Carina. It is approximately 80.6 light-years from the Sun. It is one of the stars that at times lies near the south celestial pole due to precession.

Image acquired with the Takahashi FSQ-106ED refractor and FLI PL16803 camera from Telescope Live in Heaven's Mirror Observatory, Australia.

Total integration time: 240 minutes
LRGB: 6 sub-frames of 600s with each filter.
