Description

A much more careful processing of my prior image https://www.astrobin.com/413913/C/ with added luminance frames.

This galaxy lies in the constellation of Ophiuchus (The Serpent Bearer), not far from the centre of the Milky Way on the sky. The positioning of NGC 6384 means that we have to peer at it past many dazzling foreground Milky Way stars that are scattered across this image.

Peering at a galaxy 80 MILLION light years away through Milky Way stars THOUSANDS of light years away makes for some very challenging acquisition and processing.
