Description

In this 2 1/2 hour narrowband exposure, "Thor's Helmet" kind of looks like it's dancing with its arms in the air to me!

Color mapping:

R: 0.5*S2+0.5*Ha
G: 0.15*Ha + 0.85*O3
B: O3

Boosted the saturation a bit on cyans and reduced it on the reds to make it a bit more aesthetically pleasing.
