The Wall of NGC 7000

"The Wall" of the North American Nebula in Cygnus in full narroband colours. This is my first real attempt at tricolour narrowband processing. Using Ha, OIII and SII filters. 20 exposures 10min long for each channel. SBIG 8300, AT8RC, EQ6 mount. I initially started with the classic hubble palette with the assignment of Green to Ha, Blue to OIII and Red to SII. I didn't love it especially the resulting pink stars so I started to experimant with assigning colours to the different channels and wound up with mapping Red to Ha, Cyan to OIII and Yellow to SII. Hope you like it.
