NGC6914, jewels in velvet

Larger H-Alpha regions regularly host interesting reflection nebulae, like NGC6914 in constellation Cygnus. Several young, bright stars illuminate parts of the dense molecular cloud and reveal its structure, while the remaining part hides everything as a dark nebula.

The same target can be spotted in the previous image, but with a different color rendition and additionaly collected Oxygen III.

I spent some unexpected amount of integration time into Sulphur II which only is used to generate some structures within the brighter Hydrogen regions. The S2 layer itself looks quite amazing as we can see in this crop:

To reveal these fine structures a lot of integration time was required, as Sulphur is usually fainter than Hydrogen.

For comparison the same crop from the Hydrogen layer:

While these look quite similar on first sight, some details show more contrast in Sulphur.

If you look closely, you can easily identify parts of the reflection nebula within the Sulphur layer, which are hard to spot in the Hydrogen layer.

As all images are crops only, this is the full APS-C frame taken with a focal length of 580mm:
