Description

Northern Lights / Aurora

A couple of nights ago, I took all of my equipment with me for a night of imaging. The plan was to use the Star Adventurer Pro, a 70-200mm and image Cygnus at 70mm (then blend with a foreground shot). Session went well at the start, but the corner of my images started turning more and more green and I really thought something was wrong with my camera sensor.

I turned off the tracker, and framed my foreground instead. A 1 minute exposure showed why it was so green - Northern Lights had made its appearance.

In a hurry, in -13 celcius. I swapped lens to my 16-35, removed the Star Adventurer from the tripod, put the MSM up and did a quick alignment with the laser (which I had in my pocket this time) and framed a shot.

This image consist of only two exposures. One 45 seconds for the sky, and one 60 second for the foreground. I blended the two in Photoshop.

Camera: Canon EOS 5D MKII

Lens: Canon EF 16-35 f/2.8 USM

Tracker: MSM

Sky (tracked): 1 x 45s @ ISO 800 f/4

Foreground (untracked): 1 x 60s @ ISO 800 f/4
