An image of NGC3372 taken using a remote telescope at iTelescopes Siding Springs Observatory.
10x180s Subs in each I=of the following: Luminance, Ha,OIII and SII. The sub were processed in Pixinsight and finished in Photoshop.
The Carina Nebula NGC3372 is also known as the Eta Carinae Nebula, Great Nebula in Carinae or n Car Nebula. It was discovered by Nicolas Louis de Lacaille in 1751â€“52 from the Cape of Good Hope. It is 6.5-10k ly away in the constellation of Carina, and is located in the Carinaâ€“Sagittarius Arm. It is a very large nebula of variable size over 4 times larger and much brighter than the Orion Nebula at Mag 1.
In the top right of the image we can see star cluster NGC3293 and just below the red ball is star cluster NGC3324. There are several other clusters within this nebula, at the centre of the nebula in star cluster Trumpler 16 is the most luminous star visible in the milky way WR25 (a poor name for such an important star!). Nearby is the Hypergiant star Eta Carina one of the most massive stars identifiable from Earth at 100-150 solar masses (SM). Stars this large exceed the Eddington Limit of 120SM below which the outward radiation pressure is balanced by the gravitational mass of the star. In these massive stars gravity struggles to hold the radiation and gas together, they have very short lives and eta Carinae will end in a supernova or Hypernova in the near future.
