    This one I was hunting for, for a long time. Finally.
    Good conditions! One of my best deep sky!

    M78 is the brightest diffuse reflection nebula in the sky
    and is about 1,600 light years distant.
    As a reflection nebula, M78 is a cloud of interstellar dust
    which shines in the reflected and scattered light of bright blue
    (early B-type) stars, among them the brightest, HD 38563A,
    and second-brightest HDE 38563B, both of about 10th
    visual apparent magnitude.
    M78 measures almost 4 light years in extension.
