One of the other astronomers described it as triangular and indicated the orientation. At first I still couldn't see it. But by jiggling the scope a little it popped right out at me. I was also somewhat selfishly encouraged when the only person there with less experience than me reported not being able to see it at all.
Progress is possible.
Jay looked cold that evening and left early. But they were packing up too. And by the time I walked back down the hill, my scope was the only one remaining. An unexpectedly busy night at FPK had turned into a one-scope show. I finally gave up too when I ran out of Caldwells above the horizons.
