Description

Reality is when you center on Sh2 103 with a long focal length scope there is not much "there".  This is in between the Eastern and Western Veil. 

Very difficult seeing in my location dues to humidity.  These were the best 10 h of over 20h taken. Tried to use GHS to highlight the more important structures, but they are subtle. 

Note:  for those with eagle eyes, there were small star spikes in several images due to a dew heating problem of the C11 subsequently resolved.  Described in detail in Sh2 88:

Lay of the Land from Wikipedia:

In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. The structure is so large that several NGC numbers were assigned to various arcs of the nebula. There are three main visual components:
  • The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula,= "Filamentary Nebula") near the foreground star 52 Cygni;
  • The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula") and IC 1340; and
  • Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop.

NGC 6974 and NGC 6979 are luminous knots in a fainter patch of nebulosity on the northern rim between NGC 6992 and Pickering's Triangle.

In my repeat tour of the Sh2 Objects these locals come up.
