This nebula has many names: Monkey Head Nebula, IC 2159, Sharpless 252, NGC 2175. I found only a few images of this nebula on the web. So I decided to take an image with the Moravian G2-8300 at the 12″ f/4 Newtonian with LRGBHaOIII=90:90:90:90:570:360 minutes which gives a total exposure time of 21.5 hours. Subexposures were 10 minutes for LRGB, 30 minutes for Ha and 60 minutes for OIII.
Under the menu Latest Images you will find the zoomify version, so you can watch all the details of this beautiful nebula.
