Moonlit Aurora [Explored]

I missed the big geomagnetic storm a week ago, but I still managed to get some nice northern lights during my Swiss International Air Lines flight from San Francisco to Zurich Friday night. While the bright light from the quarter Moon made the Aurora visually less impressive, it helped to illuminate the ground.

 

This is the 'first light' image with my new Canon EOS R7. I bought this camera for wildlife photography, but of course, I still had to try it at night. A crop sensor isn't my first choice for shooting in low light, but it still can produce good results.

 

Here, I combined the R7 with the Canon 0.71x Speedbooster. This adapter is officially only usable for Canon RF-mount Super 35mm Cinema Cameras, but it also works with APS-C cameras and EF-mount lenses.

 

The speedbooster increases the FOV of the APS-C sensor to almost the full frame, and the light captured is increased by a full stop. With the 28mm f/1.4 lens used for this shot, the resulting full frame equivalent, therefore, is 32mm f/1.0. The fast f-number and the IBIS of the R7 helped me to capture this image handheld.
