Alkaid's Neighbors

I mentioned Vancouver's zenith star, Alkaid, a few posts ago. In and of itself Alkaid is not particularly remarkable, but two of its neighbours in sky are. Within a couple of degrees of Alkaid are two of the most beautiful galaxies in the firmament, M51 (The Whirlpool Galaxy) and M101 (The Pinwheel Galaxy). Here are some photos from the Hubble Space Telescope (NASA/ESA).
M51 - The interacting Whirlpool Galaxy
M101 - The Pinwheel Galaxy
