Saturn images

A late Sunday night session getting images of everyone’s favourite ringed planet.

As usual – conditions weren’t ideal.  Saturn was low in the southern sky – just 11 degrees above the horizon.  When I set up the seeing was fairly steady.  I managed to get 2 avi movies and then the seeing deteriorated completely: Saturn was barely recognisable as it morphed and shimmered in the unsteady air.

A longer exposure with the Nikon D90 brought out six of Saturn’s moons.

The vertical colour aberration was caused by the low altitude refracting the light by different amounts.  Still, Titan shows a definite orange colour overall.
