Description

Starting off 2020 with my favorite deep sky object as a child.

The Great Orion Nebula (M42) and Running Man Nebula (M43) imaged last weekend.

On a good clear night, from a dark site well away from light pollution, this glowing cloud of gas and dust can be seen with the naked eye as a fuzzy patch surrounding the star Theta Orionis in the Hunter's Sword, below Orion's belt. It is probably the most spectacular of all the objects cataloged by Charles Messier and now called by their ‘M’ class numbers.
