Fig.3 - The star Atair close to the celestial equator, photographed with the Nikon Z6 and the Nikon Z 20mm f/1.8 S with different
exposure times from 30 s to 10 s. The camera was mounted on a tripod with no star tracking. At 10 s, stars are almost pinpoints
("200 rule"). Longer exposure times lead to increasing star trailing.
