M16 Eagle Nebula - July 2015

Imaged F10 on a 8" SCT. OIII and the SII data was very dim and I had to push it more to bring out some nebulosity in that spectrum increasing the noise... Hence the purple halos on the NB image. I'll reprocess the narrowband image and attempt to remove the purple by tightening stars in the SII and OIII channels.
