Amazing shot.... as all your Aurora's shots from Norge... nicely composed, superb colors and light rendering! Also I imagine about the difficult shot conditions - polar night, cold, wind... The only one proposal for such type of shots (previous and recent) - this images are... something over-sharped and around the contrast objects or on boundary's appears the thin white halos. The Nikon D800 is very hi-res camera and IMO the additional details sharping is something... excessive... May be after resizing before uploading to dA Gallery? In any way... this is the really pro photographer and amazing night scape auroras shot(s) ... Thank U!!!
