The setting is a conjectural planetary system around the factual Eta Cassiopeiae A, a sun-like star about twenty light-years away.  Eta Cass A has a red dwarf star orbiting it at Neptune-like distances; both are visible in this view from the polar regions of A's hypothetical terrestrial planet, itself a binary planet. For this portfolio, I had created a whole technological syndrome involving articulated spacecraft such as you see in the background.
