Swan Nebula is a bright emission nebula in Sagittarius, and has a clearly defined shape of a swimming swan. The nebula can also be seen as a faint spot with naked eyes.
With a help of UHC filter (Orion Ultrablock) - a fuzzy, large, arc shaped nebulocity surrounds the "swan" from NE. At larger magnifications - several dark filaments can be spotted inside the bright inner part, as well as a tiny "crown" above the swan's "head". Note: The drawing isn't oriented with north upright.
