Description

One of the most laborious images I've ever done. Despite being frequently photographed, the Ophiuchus region is a challenge on itself. Lot´ s of different brightness, colours and dynamic ranges happening in the same field.

Furthermore, I've tried to incorporate some new processing techniques. Hope you like the final result.

For the channels I've used a synthetic Luminance, which I've processed separately.

.R - 18x300"
.G - 19x300"
.B - 18x300"

Total exposure time: 4,5h
