Description

This is part of my Western Veil backyard project just got finished. Really like the details especially the "floating" O-III signals streaking over the H-alpha red base. This portion really deserves it's own edition. :) The full version could be found here: Western Veil, Pickering's Triangle & The "Funnel".
