Taken with an amatur 18cm telescope carried in my car with 145min exposure in the dark sky area near Mt.Fuji here in Japan.
This is a reflection nebula lightened by the the bright hot young stars inside which are visible with naked eyes, also beautiful to see with benoculars.
10 sec exposure will be enough to show the stars but long time effrot taking attempt is necessary to show the faint blue veil of the beautiful gas clouds.
Blue color is made of ionized oxgen and red color is made of ionized hydrogen gas.
Please view with a dark background setting clicking the round shape icon on the right bottom of the picture.
