Description

Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are toward the right in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 30 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Took just over 2 months since the commencement of the first sub-exposure!​Tried out a new processing workflow which was meant bring more emphasis on the dark and central gas structures while keeping the highlights toned down. I made a few variants of the Hubble palette but eventually settled on the good ol' traditional Hubble Palette colour grading. I finally created my own Luminance layering technique, which also brought out the sharp and cripsy details in the dark nebula region. The use of good masks were crucial for selective sharpening of the Luminance layer while the final layering was done traditionally in Photoshop CS 6.​Imaged from my balcony in Central London
