Sony A7RIV full frame mirrorless camera with
Rokinon 12mm F2.8 Full Frame Fisheye lens.
Post-processed in Adobe Lightroom and stitched 3 photos together in Photoshop for a panorama showing western sunset sky and eastern sky.
Saturday evening's sunset (3-photo panorama) with crepuscular & anticrepuscular rays arcing over the sky.
West (left side of image) sunset crepuscular rays appearing to converge on the sun.
East (right side of image) much more dramatic anticrepuscular rays appearing to converge in the sky directly opposite the sun.
Photo was taken from Chatfield State Park facing north toward Denver, Colorado, USA.
