Description

Observing conjunction of Mars and the Moon (actually, occultation of Mars by the Moon for some areas) of Dec 7-8, 2022 from Long Island, NY (handheld Pentax K-1 camera on a tripod, multiple f=300mm f/5.8 ISO800 out of which 8 were selected and merged to produce the final image). Moon is with 99.95% disk illumination, Mars is at -1.7m, 0.55 AU away / with 17 arc.sec angular diameter (just a few hours before the opposition of 2022).


The overall map of the area for occultation visibility can be found under [1, 2]:

Long Island NY wasn't too far from the area of occultation visibility, so it was a rather close (2.6 arc.min separation from the lunar limb) conjunction instead, as illustrated on simulated image below produced with Starry Night Pro Plus 8 for the moment of maximum proximity (there is also HIP23032 (+9.7m) star in the FOV that was of course completely subdued by the Moon glow):




The weather conditions for this event looked rather unfavorable right until 1h before the maximum proximity, at which time all fog and low clouds have cleared out: here is the Clear Sky chart for the point of observation 70 miles further East on Long Island, that had similar effect likely could of hours later as well):
