Explanation:
For 55 consecutive nights
Mediterranean skies were at least partly clear this
summer, from the 1st of July to the 24th of August 2018.
An exposure from each night was incorporated in this
composited telephoto and telescopic image to follow
bright
planet Saturn as it
wandered through the generous evening skies.
Through August, the outer planet's seasonal
apparent retrograde motion
slowed and drifted to the right, framed by a starry background.
That brought it near the line-of-sight to the central Milky Way,
and the beautiful Lagoon (M8) and Trifid (20) nebulae.
Of course Saturn's
largest moon Titan was also along for the ride.
Swinging around the gas giant in a 16 day long orbit,
Titan's resulting wave-like motion is easier to spot
when the almost-too-bright Saturn is
digitally
edited from the scene.
