From Procyon to Pleiades: 100º of sky with 18mm lens

I like to label my photos as a way to teach myself what to look for in the night sky. This particular chunk of sky contains plenty to keep me busy! From Procyon (Alpha Canis Minoris) to the Pleiades (M45), this wide field photo covers about 100º of sky - which is about 10 horizontal fists, or 5 wide open hands held at arm's length.

Not all of the objects are visible in this photo, but I added their positions to help me learn them. The dim ones, like the Flame Nebula, will require stacked exposures or a telescope.
