Mike, Wonderful image. M16 is a perfect match for using narrowband imaging and the Hubble Palette, otherwise the majority of the background is overwhelmed with the color red due to the extensive H II region. You certainly devoted enough imaging time to it! Looks like your remote site is dialed in nicely.
