A Night at the River
Copyright: György Soponyai

Dömös is a Hungarian village in the Danube Bend (Dunakanyar) located 45 km north from Budapest. The Dunakanyar is often considered as one of the most beautiful part of river Danube where it flows between Börzsöny Mountain and Visegrád Mountain.

I often escape from the Capital and travel here for some recreational wild camping or simply for staring at the sky in a sleeping bag at the bank of the river.

The night of 28th March 2017 was moonless, cloudless and warm so I went here for taking this seven-hour-long all-sky photo, the longest one I've made.

Photo details:

2017.03.28-29.
Dömös, Hungary

Canon EOS 5D Mark II + Sigma EF 8/4.0
218 x 120 sec, F4.5, ISO 1600

Star Trails in symmetry with a spiral petroglyph pecked into a 800 year old wall in Mesa Verde National Park. I intentionally defocus the stars slightly to bring out their natural color. All illumination on the wall is from moonlight.

While IC 2872 makes up "the head" of the chicken in many wide field images of the larger Running Chicken Nebula in Centaurus, it is rarely imaged in close up like this, with imagers favouring the area around the famous Bok or Thackeray's Globules in the brighter section of the nebula.
