Orange Peduncle Socket

Macro and Micro Picture of the Day 2020-01-07

Today's picture is an orange peduncle socket, that is, the hole left behind when the green knob on the orange is removed. This appears to have an 11 fold symmetry. We have checked a few other oranges whose penduncle sockets also have 11 fold symmetry. We're not sure if that is the case for all oranges. The diameter of the peduncle socket is 6.5 mm from outer rim to outer rim.

To compensate for depth of field limitations, this image was created by focus stacking 3 images focused on different parts of the peduncle socket. The Hugin Tools software was used for this.

Equipment used: Canon EOS Rebel T5i with 35 mm long extension tube.
