Red Planet Meets Blue Planet

Mars (the bright yellowish object) just 18 arc minutes from Neptune to the left, on the evening of December 6, 2018. They were closer together several hours later but that was when they were below my horizon. Both were in Aquarius for this conjunction – indeed Neptune isn’t going very far from this spot for many years; it’s Mars that’s doing the moving.

 

This is a stack of 7 x 90-second exposures blended with one short 20-second exposure for Mars itself to prevent it from being too overexposed. All with the A&M 106mm refracrtor at f/6.2 and Canon 6D MkII at ISO 400, and with the Hotech field flattener.
