I live in a Bortle 8 location, where the NELM is about 3.8 at the zenith. (SQM ~18.66)
Very unfortunately, my trip to a Bortle 4 location (SQM ~ 21.2) has coincided with the Full Moon. Today (ignoring the partly cloudy conditions with moderate transparency) the NELM is about ~4 at the zenith.
Before I called it a day I tried M57 in my portable 100mm reflector. I couldn't make out the Ring Nebula, at all.
Cygnus & Lyra were away from the moon and slightly better than home (we're talking naked-eye Sheliak, Sulafat & Albireo ) but Cassiopeia, Pegasus and Andromeda were utterly washed out. This is is especially annoying as they are behind a house at home.
Is it worth observing when the moon is about 10° up? What can I observe, if anything, better than i do at home? How will globs, open clusters etc be affected?
And a final question: what am I missing out on? (some of the milky way maybe (?) .Frustratingly, I've been to a Bortle 3 location before on holiday, before I took up astronomy, and didn't look up!
