      NGC 3293

      The prime focus of this image is the open cluster NGC 3293. Also known as the ‘Gem Cluster’ it was discovered by Nicolas-Louis de Lacaille in 1751 and is approx. 8000 light years from Earth. It consists of more than 100 stars brighter than 14th magnitude in a 10 arc minute field.

      To the right is the emission nebula Loden 153, although there are references to this nebula on line there is little detail to be found.

      To the left of NGC 3293 is the emission nebula IC 2599, known as the Gabriela Mistral Nebula, surrounding the small open star cluster, NGC 3324. Finally is part of the massive Carina Nebula, NGC 3372.This nebula is one of the largest diffuse nebulae visible, four times larger and brighter than the M42. It is located in the Carina-Sagittarius arm of the milky Way, approx. 8.500 lightyears from Earth.
