Sunspots beside the spire | Astronomy Magazine
Chirag Upreti from New York City
Active region AR 4475, a cluster of sunspots that emerged June 22, drifts beside the broadcast mast of the Empire State Building. Sunspots are patches of intense magnetism on that Sun’s surface that are slightly cooler — and therefore not as bright — than their surroundings. Upreti shot a single 1/400-second exposure at f/14 and ISO 640 with a Sony mirrorless camera and zoom lens at 600mm, plus a 2x teleconverter for an effective 1200mm focal length.
