The Carina Nebula (Hubble Palette version)

In this image, taken by +Dylan O'Donnell from his own Observatory in Byron Bay, Australia, using an 11″ Celestron F2 RASA telescope and a QHY9 mono CCD you can see the famous Carina Nebula (NGC 3372, Caldwell 92). It is an emission nebula located in the constellation of Carina (https://goo.gl/ojyHNx), between 6,500 and 10,000 light-years away from Earth. It has a diameter of about 250 light-years.

In this image Dylan assigned different narrowband images to the three color channels of a digital image. The "Hubble Palette" he used, shows you the emission of sulfur in red, hydrogen in green, and oxygen in blue.

The Carina Nebula is a stellar nursery with lots of open star clusters (https://goo.gl/fM4XdP) and ongoing star formation (https://goo.gl/Mn2Zxf). Take a look at Trumpler 14, one of those star clusters:

NGC 3372 was discovered in 1751–52 by French astronomer Nicolas-Louis de Lacaille (https://goo.gl/8nChvA).

What is an open cluster?

An open cluster is a group of a few thousand stars that have their origin in the same stellar nursery and are of roughly the same age. They are bound together by their gravitational forces. More information here:

What is an emission nebula?

An emission nebula is a cloud of ionized gas (often by ultraviolet radiation from nearby stars) emitting light of various colors, in case of HII mostly reddish-pink (viewed in natural colors). More information here:

Star Stuff 2017

Dylan will be one of the speakers at Star Stuff 2017 in Byron Bay, Australia, on June 24th and 25th, 2017. If you are interested in "Star Stuff" (who isn't, duh?) and want to experience some really interesting Keynote Speakers you can find more information here:
