Went out this month to photograph the C/2023 A3 comet, and managed that. However it was the fog rolling in below which caught my attention. I had zero visibility in my viewfinder / live-view. So I shot completely in the dark.
However I did minor adjustments on my geared-head to get the composition I wanted.
Unfortunately I did not photograph the fog immediately, since I thought it was just snow... But I realized it was fog when it changed shape over time.
