Nice work Benny. You've obtained a good balance of the SHO palette. May need to perform some further layering work to manage the dynamic range a little better. Lovely wisps of nebulosity present in the outer regions.
Great Photo.
The wisps of nebula that some people have commented on is actually a Wolf-Rayet Bubble surrounding a WR star. In the image you can even see that the nebula had a different colour than the rest of the complex. It is associated with the Eta Carina nebula complex. It is one of the many overlooked objects in the sky because that are located NEXT to bright and interesting objects.
If this nebula was located in a different place in the sky it would be viewed as a WOW object. If you use a photo like this you can trace the nebula in a scope of about 6" or larger.
