M33 - The Triangulum Galaxyby *ZeSly

Photography / Animals, Plants & Nature / Weather and Sky

M33 is a nearby galaxy located at approximately 3 millions light-years in the constellation of the Triangulum. It is relatively large in the sky but faint. Unlike what is written in Wikipedia, it is not visible with the naked eyes. Or you must have an Excellent sky and a very very good vision. Even with a telescope, this one should be big enough to see more than a faint spot.

She is in our local group. She is one of our neighbor and in 2 or 3 billions years she will enter into collision with our galaxy and Andromeda Galaxy. Don't worry it's not dangerous.

Some clouds at beginning cause the rejection of the 8 first exposures. After 0h30 everything worked quiet well.}
