Alright, one thing caught my eye here. Is the particularly well lit ruddy dust patch in the middle of the "Gulf" anything particularly interesting?

HBC 722!!!!! I remember being obsessed with this back in 2010. You can see a closer view of it by Antonio Sánchez

Cool. 2010 was when it had an outburst of some kind! Here's a more digestible (for me) to read article about it:

Green has found that this protostar, called HBC 722, is situated in a tangled web of gas and protostars tightly packed into a small area. Green’s research is published in today’s issue of The Astrophysical Journal Letters.
HBC 722 lies 2,000 light-years away in the “Gulf of Mexico” region of the North America Nebula (NGC 7000), in the constellation Cygnus, the swan. In early 2009, it appeared to be an ordinary young star in a cloud of similarly young stars. Like most stars less than a few million years old, HBC 722 is surrounded by a disk of gas and dust, perhaps beginning to form a planetary system.
It began to brighten, slowly at first, increasing dramatically during the summer of 2010. By late September 2010, it was 20 times brighter than it had been the year before. Since that time, it has slowly begun to settle back down.
