Description

A bycatch and test of my old EQ3 mount - without guiding and at the same time a test of the 80mm /1.9 @/4 Mamiya medium format lens with a full frame camera.
Orion was just over the horizon and very close to my neighbor's house roof. The red area in the lower right corner is probably due to chimney smoke.
