False Cross and Gamma Velorum

The asterism of the False Cross in Vela and Carina, at left, with Gamma Velorum, a bright blue supergiant star, at right. In between are faint arcs of nebulosity in the Gum Nebula. To the left of Gamma Velorum is the open star clister NGC 2547. Below the bottom star of the False Cross, Epsilon Carinae or Avior, is the large naked-eye star cluster NGC 2516. To the right of the right star of the False Cross, Delta Velorum, is the loose open cluster IC 2391. This is a stack of 5 x 2.5-minute exposures with the 85mm Rokinon lens at f/2 and filter-modified Canon 5D MkII at ISO 2000, plus one exposure layered in taken through a Kenko Softon A filter to add the star glows. On the iOptron Sky-Tracker, from Tibuc Gardens Cottage at Coonabarabran, Australia.
