Description

A 1280 x 1280 pixels excerpt from a 6000 x 4000 pixels DSLR image (90 subs x 30 sec each @ISO400, 20 darks at f2 but stopped down with a Ø52mm LP filter) showcases exceptional optical quality of the prime lens in terms of resolution. The faint nebula opposite of the Orion looks like the witch head. No tricks involved :-)
