I shot this incredible area of sky with a Stellarvue SVA-130T triplet apochromatic refractor on loan from Stellarvue for a review in the November 2016 issue of Sky & Telescope magazine.
It was shot with a full-frame unmodified Canon 6D on loan from my good friend Joe Stieber.
It is a composite stack of 30 five-minute exposures at ISO 800 at f/5 with the f/5 with matched SFFR.72-130 Focal reducer / Field Flattener.
