The Dust of Cepheus

Here is an image of the stellar dust surrounding NGC7023, The Iris Nebula. This is an image I've been working on for almost a full year due to two reasons: the extreme contrast between the dust and stars and problems with the data set I gathered. Boy, I'm so pleased to have finally resolved a great image out of the data I captured. I used a new technique I'm experimenting with called relinearization by some. This allows me to remove the stars using Starnet before officially stretching the data and effectively transform the image back into its linear state for processing steps that work best with linear data. This allowed me to reveal the faint dust while nicely controlling the stars. I'm very pleased with this image, and I'm gonna apply this technique to another troublesome data set I have and see what I can make of it! Until then, I hope you enjoy :)
