摘要
A test observation using a Nb-Al-AlOx-Al-Nb superconducting tunnel junction detector was carried out using a small commercial optical telescope. Single photons of visible wavelengths were detected from alpha Lyr, alpha Boo, and Jupiter, and pulse-height distributions were obtained. The observed spectra roughly agree with predictions.
