Lobster Claw and Friends

About This Image

Taken with narrowband filters, then processed each filter separately to the point of being stretched. Used Pixel Math to create HOO and used NBCM script to colour the Sii data a deep yellow colour. Used ImageBlend script to combine the Sii with the HOO to generate a HOOS palette. Fine tuned the background using a luminance channel generated from the narrowband channels combined as a super-luminance. Stars are RGB stars.
