ASTROTRACER Type2
Shift the camera’s image sensor half the speed of Type 1 in synchronization with the movements of stars to prioritize capturing the landscape and stars in a good balance.
ASTROTRACER Type3*
A simplified equatorial function that enables to track and capture celestial bodies without using GPS. Before actual shooting, a preliminary shot is captured automatically, enabling celestial body tracking from star movements.

In such situations, it is recommended that users select the Type 1 or Type 2 mode. When used with interval shooting, it is possible to perform multiple main exposures with a single preliminary shot.
＊Time exposure of the mode dial B (Bulb Exposure) is available (Normal bulb exposure is not possible).
＊Not compatible with fisheye lenses.
＊Only use the zoom lens at the wide or telephoto end. However, the following lenses can be used at any zoom position.
