      Eta Carinae, Keyhole Nebula, and Carina Nebula

      There's so many objects in this field, there's almost too many to count. First, there's Eta Carinae, a highly luminous hyper giant star with a mass of 100-150 times that of our Sun and a luminosity about 4,000,000 times the Sun's. Next, to the right of Eta Carinae, is the Keyhole Nebula which is a small dark cloud of cold molecules and dust with a diameter of about 7 light-years. Just to the right of the Keyhole Nebula is the d

      Defiant Finger, a small boy globule. Above and to the right of the Keyhole Nebula at about the 2:00 position is the open cluster Trumpler 14, with a diameter of about 14 light-years. Above and slightly to the left of Trumpler 14 is a gas pillar known as Mystic Mountain which is about 3 light-years in height.

      These are just a few objects in this image which is a blend of RGB and SHO subs @ 300s with a total exposure time of about 5 hours.

      Hope ya like it!
