NGC1955

NGC 1955 is an open cluster associated with an emission nebula located in the Dorado constellation. This nebula is part of the H II region which is part of the Large Magellanic Cloud and was discovered by James Dunlop on August 3, 1826.

Its apparent magnitude is 9.0, and its size is 1.8 arc minutes - which is nerd speak for dim and weeny.

This image comprises 77 separate images, each 10 minutes long in the Hydrogen, Oxygen and Sulphur wavebands. These 77 images are stacked on top of each other to increase the signal and reduce the noise.

The result is the lovely blue hues of the ionized Oxygen gas intermingled with the golden orange of the Hydrogen and Sulphur compounds. It may not smell too good, but it looks lovely.
