Description

I became interested in the area NW of the Cone/Christmas Tree after seeing an even wider field APOD. This is 4.5 hours taken with the Borg 55 Triplets and Chroma 3nm filters. The Milky Way is fast disappearing as we plunge into the darkness of Galaxy Season, so I am not certain to be able to gather sufficient OIII and SII before it disappears for a while.
