Caption: On the left is a resolved image of Betelgeuse from the Hubble Space Telescope (HST) and on the right is a non-HST wide-FOV image of constellation Orion (with Betelgeuse marked by an X mark). The lines joining the stars are NOT present on the sky, of course.
Features:
The other two are the Big Dipper (officially an asterism in Ursa Major) and Cassiopeia (the Big W). Both are in the northern sky and are circumpolar constellations for those at mid-northern latitudes and farther north. Hence, they are all-year constellations for those regions.
