Here's a smaller area of the sky from my urban front yard. I intentionally cropped off a very obvious part of a constellation.

 

Enjoy!

Northern part of Orion

Judging by the time of year, I would say Arcturus, Rasalhague and Rasalgethi are the three brighter stars. It would be upside down. Keystone of Hercules, head of Serpens. 
 

But a lot of stars are missing, and the patterns are a bit off. It’s just not a good enough photo for precise plate solving.

 

As for the head of Orion as a possibility, it seems like far too much sky for that.

Kudos to Sketcher. I guess your hint about a significant part of the constellation being cut off was no exaggeration.

 

The asterism that includes lambda Orionis with that little faint trail of stars is very distinctive. However I never really noticed that horizontal chain of stars below Bellatrix before. This explains why I couldn't shoehorn the stars into the pattern around Arcturus.

You got it!

Collinder 69 (the Lambda (λ) Orionis Cluster) was the giveaway.

Lambda Orionis (Meissa) lies between Betelgeuse and Bellatrix.
