Sh2-171
S-II, H-alpha and O-III as a Hubble palette
H-alpha, O-III, synthesized Blue as a "Natural" color
H-alpha

Sh2-171 is an emission nebula in Cepheus.
I have shot few objects from the Sharpless catalog before, I find them interesting and
not too common as an imaging targets.
Here is three versions, first is a narrowband color version in Hubble palette,
second is a "natural" color version with synthesized green from H-alpha and O-III.
Third, black and white, is a hydrogen alpha channel only.
