I Have To Say It,

what a stunning picture,

it was taken last year in coldest October by photographer Johannes Holzer who braved the winter cold to setup a series of long-exposure shots along the the Isar, a river in Southern Germany,  Holzer says the photo was done with the sky "on a Sony A7r and Vixen Polarie Startracker, one additional shot for the landscape without [a] Startracker, [and] underwater was done with a Canon 5Dm2 with an EWA Underwater case." all of the pictures were then spliced together, Holzer specialises in Milky Way photography and landscapes, you can see much more of his work and other photographers on Karwendelbilder, what an incredible photograph.
