    Description

    It's all about that little band of dark clouds outside an otherwise featureless galaxy.

    I'm working on retaining star color. It seems that keeping the highlights down on the initial stretch is the key. This more limited stretch is also helping with controling noise.

    65 subs, L25 R13 G14 B13, all 600 seconds. 10.83 hours.
