Description

Galaxy Quest 2019 continues. I *really* messed up during my acquisition of the blue and green (I made the same flockboard mistake that killed my star colors on the Medusa Nebula). Special thanks to Bob Andrews for rescuing this one! (Because I really didn't feel like capturing more on this...) Still, star colors were unsalvageable for the most part.
