Description

North American Nebula and Pelican Nebula captured under Bortle 6 skies. The left half of the image and especially the lower left shows a color hue indicative of OIII nebulosity (which also shows up in the individual frames of the stack and the stack). I had some problems with OIII acquisition (mis-matched flats). So not sure if it's actually nebulosity or data issues. Regardless I am leaving it in there since the rest of the image (OIII frames and stack) seems to show no such artifiacts, indicating that acquisition itself might be fine.
