The faint filaments of the giant supernova remnant known as the Cygnus Loop are visible in this image obtained with the wide-field view of the Mosaic camera on the WIYN 0.9-meter telescope. Because of its immense size, it contains several individually named objects, including NGC 6992 and IC 1340 on the left side as well as NGC 6960 and Pickering's Triangle on the right. // T. A.
