Taken from my home's rooftop in light-polluted San Diego. As Murphy's Law would have it, the day I setup the city had installed a new high-pressure sodium street light that ended up shining onto my roof. Amazing what a 6nm sliver of bandpass can give you in these conditions. The filter is an Astrodon.
