Stenocactus albatus

This is a 2x close-up of Stenocactus albatus flower. 
Taking pictures at higher magnification becomes elaborate - the very shallow depth of field requires taking several shots, scanning the subject with the focal plane, and then reassembling them into a single image using post-processing software. This image is a superposition of 6 shots, needed to accommodate the stigma lobes depth.
