As a tech writer, I specialize reviewing tech including cameras and camera phones. Here is a selection of my recent work from my back yard with Aurora Borealis, to Greece, Iceland and Jashua National Park in California and Lake Louise.

In the circular streaks, the center star is Polaris often called North Polar Star.

Typically, exposures are several hours long for one frame. Straight lines are passing airplane trails or occasionally, comets, even Aurora Borealis!
