IC 59 and 63, often referred to as the Ghosts of Cassiopeia, are twin combination reflection / emission nebulae located about 600 light years away in--shocker--Cassiopeia.  They owe all of their nebulosity to the intense radiation emitted from the star Gamma Cassiopeia, located only a few light years away from them.  A few light years, you say?  Isn't that, like, a really long ways?  Sure, but Gamma Cas ain't your ordinary star: it's what's known as an eruptive blue-white subgiant variable star.  Translation: it's completely insane.  Like a total Chad among stars.  It sports 55,000 times more luminosity than our puny Sun, is 19 times more massive, has a radius 14 times greater, and oh by the way it also rotates at about 300 kilometers per hour, or 150 times more rapidly than the Sun, because it clearly has something to prove.  It has not yet been confirmed that it has radioactive planet-sized sharks swimming through its plasma, but I think that’s a foregone conclusion at this point.  Anyway, it's the reflected light from this absolute unit of a star that gives the Ghosts their characteristic blue shimmer.  The radiation is so great, even at that distance, that it has ionized the edges of the clouds, creating the eerie pinkish/reddish glow we see surrounding them.  It’s this story I tried to bring out in the image, particularly the blue reflection elements. 

Less-than-stellar attempts at humor aside, processing this was very difficult.  You've got this incredibly bright star.  You've also got dim blue reflection elements surrounded by pinkish Ha emissions.  And you've got an incredibly busy, potentially distracting star field.  I was lost so far down the rabbit hole editing this that I kind of blacked out and don't remember every step, but here are the broad strokes that made the most difference:

1. Create a darker, stretched RGB image that is brightened only to properly expose for the star field and the Gamma Cas brightness that I want.
2. Create a copy, and run StarXterminator on it.  Brighten the leftover nebulosity to taste, while dimming any leftover star artifacts.
3. Use Blend script set to screen blend to combine this starless nebulosity with the darker star field / star.
4. Iterate on this until madness ensues.

There is a lot of color / brightness tweaking to taste in there too, but that's the core of what I did to try and marry the brightened nebulosity with a star and star field that didn't overwhelm the image.  Hopefully it did at least some measure of justice, but even if it doesn't, I'm done with this for now and need to move on before my mind touches the void.  All criticism and commentary welcome.
