NGC 2174, the Monkey Head nebula (BiColor)

NGC 2174, the Monkey Head nebula
NGC 2174, or the Monkey Head nebula, is an emission nebula in the constellation Orion located around 6,400 light years from Earth. 
This is a bicolor image taken through Hydrogen alpha and Oxygen 3 filters.  A "synthetic green" channel was created by using data from the Ha (Red) and OIII (blue).  My plan is to add SII data to create the Hubble palette and to also image through Red, Green and Blue filters to correct the star colors.
Ha 30 min subs x 6 (unbinned)
OIII 30 minute subs x6 (binned 2x2)
Imaging telescope:  Explore Scientific 127mm CF APO refractor
