Thanks to the endless clouds here I could finish my Ghost Nebula project. I used my ASI178 mono for the narrowband frames, here in Hubble palette colors, and my Sony NEX for the RGB portion (stars only).
And I found a rather cool way to imitate the typical PI look-and-feel of the stars. It's simply a combination of a slight gaussian blur of the brightest stars and a strong saturation enhancement in PS. What do you think?
