What this latitude gives you
From 38.6° north, anything above declination +51.4° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -51.4° never clears the horizon at all.
Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.
We do not hold a measured Bortle class for this site, so treat the sky as unknown until you have taken a reading of your own.
