Description

M33 The Triangulum galaxy from the constellation Triangulum from last night, before the dreary December weather returns. Some times referred to as the Pinwheel galaxy, but that name is used for Messier 101. Third largest galaxy in our local group of galaxies.

Also visible are several H II regions, the largest is more than 1500 light years in diameter. Which would put our Orion Nebula to shame at only being 24 light years in diameter.
