Description

This representation of the Pacman Nebula is constructed from camera captures I made using four filters (R, Ha, O3, and L). The captures were stacked and ultimately converted into a single RGB image using Photoshop. The merging into the RGB channels is based on the Hubble palette and my own judgment: L is processed as Luminance, R as the red channel, Ha as the green channel, and O3 as the blue channel. Exposure ratios were individually optimized for each channel to make each layer visible. As a result, the final spectral color proportions in the image do not precisely correspond to reality.
