Thank Paco and Colin for the comments, I really like your desription of the urban dobbelganger, Colin.
The conjunction image was easier than one would think as with Mars being so close now, exposure of Mars and the Moon was matched perfectly (I used 1/60 sec at f/10 and ISO 160 for both the stacked Mars and stacked Moon takes - intensity at conjunction one month before closest approach was not much different.)
BTW I initially aimed for higher magnification for that take, using the AW1, but after a number of captures I discovered that the Bahtinov mask had been forgotten on the lens! Then the distance between them had increased enough to not fit diagonally within the frame any more, so I reverted to D500.
