The star Asterope
My favorite signal of winter is the magical faint glow that glimmers in your peripheral vision but fades to a blur when you gaze head on. Magnification reveals several bright blue stars burrowing through long filaments of ionized gas and dust. The brightest of these are the famed Seven Sisters or Pleiades.

One of my favorite winter targets, the Pleiades are easily visible as a bright cluster of stars that resemble a 'tiny dipper.' You can see their faint bluish/purple glow with the naked eye and the Seven Sisters are photogenic and multiple focal lengths. This is a series of broadband RGB long exposures to bring out the subtle dust and nebulosity that surround this young group of stars.
