Description

This image is a combination of RGB data obtained with an ASI294MC Pro one-shot color camera and monochrome images using H-alpha and OIII filters and an ASI1600MM Pro camera. H-alpha data was used to enhance the red channel and OIII the green and blue channels of the original color image.  The OIII filter I used was an Orion filter, which caused the extended blue glow around brighter stars.  I have since switched to a ZWO OIII filter, which has the same bandwidth (7 nm) as the Orion but does not introduce aberrations of bright stars.
