    Description

    Lynds Dark Nebula 1251, including several HH objects and nice little spiral galaxy peaking through the obscuring molecular cloud.

    I enjoy dark nebulae as a nice detour from the reds and blues we usually encounter in the sky. A nice dirty brown to keep things interesting!

    This one is quite large as I've only captured about a third of it in my FOV.
