"The Running Man Nebula NGC 1973/75/77" taken November 21, 2015 from Mount Pearl, Newfoundland.   Equipment - C11 on EQ8, Canon 6D (modified) and LPS-P2 filter. Autoguided using ED80, QHY5LII-mono and PHD2. Images captured with assistance of BackYardEOS, stacked and processed in PixInsight. Stack of 24, 120-second subs @ 6400iso (48min total integration time).

It is mostly a reflection nebula with some emission (and dark) nebula as well, and is located right next to M42 - the Orion Nebula.

"The Horsehead Nebula - Barnard33" taken December 30, 2015 from Mount Pearl, Newfoundland.  Equipment - C11 on EQ8, Canon 6D modified) and LPS-P2 filter. Autoguided using ED80, QHY5LII-mono and PHD2. Images captured with assistance of BackYardEOS, stacked and processed in PixInsight. Stack of 21, 240-second subs @ 6400iso (84min total integration time).

This nebula is located right next to Alnitak - the left most star in the belt of the constellation Orion (located just off left edge of image). The dark area forming the appearance of a horse's head is actually caused mostly by thick dust blocking the light of stars behind it. Bottom left of image is a reflection nebula NGC2023.

"The Monkey Head Nebula NGC2174" taken January 5, 2016 from Mount Pearl, Newfoundland.  Equipment - C11 on EQ8, Canon 6D (modified) and LPS-P2 filter. Autoguided using ED80, QHY5LII-mono and PHD2. Images captured with assistance of BackYardEOS, stacked and processed in PixInsight. Stack of 30, 240-second subs @ 6400iso (2 hours total integration time).

This is an emission nebula in constellation Orion (towards Gemini) and is associated with open cluster NGC2175. The young bright energetic stars ionize surrounding hydrogen gas - the red colour occurs largely due to the re-capture of electrons by Hydrogen ions (some resultant net energy released at a wavelength we see as red light).
