@lighteye. Got some time to find initial file, but well :) That was Canon 6D + manual Samyang 14mm lens. 30sec exposure with 5000ISO

@lighteye. Normally to catch the waves of lights need much more shorter exposure time, maybe some 5 sec. Northern light is very rare at Lithuania to be such strong and that was first trial. Second time I got used shorter time to feel the difference ) Will post later on the result
