A Desert Bighorn that I photographed at Valley of Fire State Park in Nevada. There are a few Bighorns in this Park and it is rare to be able to get close enough to get a photo. Camera was a Canon 7D Mk II with the Canon 500mm f4 lens on a tripod. Settings as follows. Aperture was 5.6, speed was 1/500 sec and ISO was at 1600.
