I look for Plato's craterlets every month or so but never see them (always see e and f in the Trapezium). Is there a secret to spotting the craterlets? I'm assuming you bag them on day 8.5 or so of the lunar cycle, but no luck. I guess with the moon quite low and it's still turbulent in the early-ish evening doesn't help!
