Also, one needs to be quite careful when observing during moonlight. If
you
turn and accidentaly look at the moon, your night vision will go down.
Your
limiting magnitude will be much lower for the next half hour, often
without
even realizing it. This is one reason why I also prefer to plan my
observations away from the moon unless a major shower is predicted. When
observing with moonlight or any local light pollution, best thing to do
is
to find some kind of shield (fence, trees, car or a big umbrella,...). My
new backyard (still east of Ottawa, ON) looks acceptable to observe
except
for a bright streetlight a bit further from a gaz station. I can get
around
this by throwing an old blanket over the fence to hide the glaring thing.
