Comet in a Crystal Ball

Comet NEOWISE (C/2020 F3) has undoubtedly become one of the best phenomena in recent years, but it is already moving away from us. That's why I decided to keep this comet together with the Big Dipper for eternal memory in this crystal ball. The town in a background is Třinec (Trzyniec) in Czech Republic.

 

Technique:

I attached the crystal ball together with the base to a small tripod. The camera was mounted on the second tripod significantly lower than the ball itself and at an angle that corresponded to reality, and the comet was thus engaged. The distance of the camera from the ball was about 1.5 meters. To focus inside of the ball, I was moving my focus ring slightly while taking pictures in between to find a perfect spot, because the stars were not visible in a ball when zoomed in with Live View.

 

Gear:

Canon EOS 6D Mark II + Samyang 135 m f/2

 

EXIF:

10 x 6” f/2.8 ISO 6400 | for the inside of the ball, stacked for noise reduction

1 x 30” f/4 ISO 1600 | for the outside of the ball to make it sharper

 

Date and Location:

22nd July 2020 | 22:58 CEST | Loučka (835 m), Bystřice, Czech Republic
