The skies most magnificent example of a "barred" spiral galaxy, NGC 1365, is a photogenic target this time of year.
Conditions on the mountain during data capture were excellent and have allowed some fine details to be captured,
including many clumps of giant blue star clusters and associated pink emission nebulae, dotted along the main
spiral arms. An intricate web of fine dust lanes is seen near the galaxy core and along the central bar.
NGC 1365 is 75 Million lights years away, in the constellation of Fornax (The Furnace).
