Great Nebula in Carina

Imaged before dawn this morning with the new Canon 70 – 200L f/2.8 @ 200. This was a stacked image (Deep Sky Stacker) using 50 light and 50 dark frames @ 20 sec each frame & ISO 1600.

The Keyhole Nebula can just be seen at the centre of the image (refer to earlier post … “Racing the Dawn”). The Gem Cluster is clearly visible above the nebula.

This first magnitude nebula is one of the largest diffuse nebulae in the sky. Although it is some four times as large and much brighter than the famous Orion Nebula, the Carina Nebula is less well known, due to its location far in the Southern Hemisphere. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth.
