really! I did not know that... got my son in law a big telescope for xmas a few years back.. he's a budding amateur peeping tom.. err.. astronomer. We've had some pretty good luck over on fire island in mid to late fall when the humidity is low. Never had quite as good results as what your getting. A couple of trips up to Vermont viewing from higher altitudes in lower light situations... WOW. WOW.. WOW.. like in the desert when I was a kid. It was like you were IN space. fantastic!
Good times.. enjoyed it immensely.. love learning new stuff, the boy is a good teacher.
