IC2169 and the Cone/Foxfur area

This image was particularly difficult to process, as it has an emission nebula and two major reflection nebulae. But I like the way it came out, as my idea was to show the contrast between IC2169 (Dreyer’s Nebula), a reflection nebula, and Sh2-273, the huge Cone/Foxfur nebula area.
