Description

This is my first experiment with running two full rigs at once. All was shot from my backyard in Somerville, MA (Bortle 9).

H-alpha: ZWO ASI-1600MM-C and Canon 200mm f/2.8 L wide open.
RGB: Nikon D800 (Mod) and Stellarvue SVQ86

This is part of a much larger mosaic I am working on, but I wanted to do a version where the double cluster was emphasized.
