Simeis 3-188 - Pickerings Triangle - NGC 6974 and NGC 6979,
part of the Cirrus Nebula in the constellation Swan |
|
Object description:
Our image shows in
detail Pickerings Triangle, sometimes called
Pickerings Wisp. Pickerings Triangle is a
sub-region of the Cirrus Nebula and forms the northern part of the supernova
remnant in the constellation of Swan. |

In
the various literature available, one often finds the designation NGC 6979 for
Pickering's Triangle, but this is incorrect, because NGC 6979 lies to the east
of it. The correct designation is Simeis 3-188. The nebular region was named
after the American astronomer Edward Charles Pickering.
Further, our
image shows NGC 6974 and NGC 6979, which are
brighter nodes in a fainter nebular region on the northern edge between NGC
6992 and Pickering's Triangle.

mosaic with a detailed description of the Cirrus Nebula by us is
