Triangulum Galaxy – M33

The Triangulum Galaxy (M33, NGC598) the third largest member of the local group, with its larger sisters the Andromeda Galaxy and our Milky Way. It consists of 40 billion stars, really small compared to the 400 billion of the Milky Way and the 1 trillion of the Andromeda Galaxy.

This in an LRGB image of composed of 16 x 900 sec subs for each, luminance, red, green, and blue using the new and wonderful data from Deep Sky West. I did the processing with true plus synthetic luminance, keeping noise reduction at the minimum not to destroy the granularity in the galaxy. I will add Ha data later, although Ha regions are quite prominent already.

Exposure: LRGB, (16,16,16,16) x 900sec Date: 2015-09-11…19
