| Description | Should have been a straight forward capture on a "clear" night. But a layer of high clouds was illuminated by a 96% moon, and that meant details were blurred. This 10m30s capture was actually better than the 40m capture I attempted. Another discovery by William Herschel, this one on February 15, 1786 |
