Photographer Captures Canadarm2 in an ISS Solar Transit for First Time

Well-known French astrophotographer and amateur astronomer Thierry Legault released this 50-second video showing an ISS solar transit he just captured. It’s notable for being the first time the ISS’s Canadarm2 robotic arm has been photographed during a transit.

Legault was shooting with a Olympus E-M1 II mirrorless camera mounted on a CFF 200mm f/8 APO refractor telescope (aperture diameter 200mm and focal length 1610mm) and a Baader Herschel solar wedge.

Zipping through space at 16,500 miles per hour (27,000km/h), the ISS passes across the face of the Sun in just 0.6 seconds from Legault’s vantage point on Earth.

In addition to the first-ever transit photos of Canadarm2, Legault also managed to capture a view of the new SpaceX Crew Dragon capsule that brought two American astronauts to the ISS in late May 2020.
