M36 is one of three relatively bright open clusters in Auriga, nestled in between M37 to the east and M38 to the west. M36 is the smallest of the three and is a tad sparse, but it does very well in small telescopes and is one of my favorite stops with my little ETX-60. If you look closely you will see a little puff of nebula on the right edge of this field; a beautiful, small, red emission nebula, NGC 1931.

M36 is currently well placed high in the northeast during the early evening.
