The photographer in question is Fritz Hemmerich and he's using a 14" Hyperstar (F/1.9), so it's not just a 14" telescope, it's a super-speed astrograph. It was also shot in Tenerife at 1200m, so I'd wager the sky was as black as black.
Please in future post all the details, especially the name of the original photographer.

Orion Nebula complex, DSLR (only IR-block-filter) exposed over an hour, no calibration (no darks, flats, bias or bad pixel mask), 65 x 1/3 sec (for the center) and 200 x 15 sec (!!) for the outer structures, Hyper star 14 ", Sony A7s (modded), ISO 3200, no cooling, no guiding. This is just a quick-and-dirty processing. I don't like the halos of the brighter stars. I will next weekend, when I have time, edit it thoroughly.
Location: Tenerife, 1200 meters altitude
Time: November 3, 2014 between 4: 30h and 5: 45h"
