Canon EOS 5D camera at ISO 3200, 100-400 mm lens at 400 mm, composite of 1-minute exposure f/5.6 and 2-minute exposure at f/11 to prevent Mars' glare. All system piggybacked on an 8" Meade LX10 SCT.
Mars at opposition passed 2.5 degrees north of bright open cluster M35 and its companion NGC2158. This is the second close pass of Mars, thanks to its retrograde motion, the first was in early October and the last will be in mid-March.
