|More bows just 8 days later ~
Zbyněk Černoch captured 3rd and 4th order bows on 18th August '14 in Czech Republic. Here he repeats the feat on 24th August.
His latest images show the benefit of searching for these faint low contrast bows against a background of fairly uniform dark cloud.
When there is a bright zero order glow and rainbows are likely, shield the camera from direct sunlight. Point it 40° away from the sun against dark cloud. Process even unpromising looking images. All images ©Zbyněk Černoch
