This is my first attempt at a true SHO or Hubble Palette image. I faked one a couple years ago but this one is real. I used two complementary dual narrowband filters, one Sulphur II and Oxygen III, the other Hydrogen Alpha and Oxygen III with a shot color ASI533MC Pro camera. SII and Ha are both red, with the former being redder. In the SHO palette, Sulphur goes to the red channel, Hydrogen to the green, and Oxygen to the blue although some people mix them up a little bit. Shot at the River Ridge Observatory, Friday night.
