This star field photograph has captured around northwest part of Ursa Major with span of about 11×15°.
Two elliptical lumps in left hand side are M81 and M82, as you can see extraordinary dimmed molecular clouds are spread around this field.
Especially there is a comparatively thick and stripe-shaped part of cloud LBN683 in northwest of two major galaxies.
It's known that the heaven includes many other such dimmed molecular clouds.
