The heart of the photo mount is a stepper motor that compensates for the rotation of the sky by rotating the axis of the mount ("hour axis") at the speed of the stars ("sideral"). This way, the camera always remains focused on the desired area of sky.
For this to succeed, the photo mount must be aligned as follows: Simply aim the integrated polarscope at Polaris and the hour axis of the mount is aligned parallel to the Earth's axis.
With the ball head with quick release plate, you can quickly attach all cameras with the usual photo thread (1/4" and 3/8") and align them to the desired sky area.
In addition, the camera only needs a setting option for long exposures and, of course, a lens. Typically achievable exposure times with good tracking accuracy are as follows: 16mm-35mm wide angle lens: 10 minutes (600 seconds) or with a 200mm telephoto lens: 5 minutes (300 seconds).
The illustrations on the right give an impression of the tracking accuracy at different focal lengths.
Battery powered: A small battery bag is included in the scope of delivery. Optionally, a power supply unit can also be connected: 6V DC socket 5.5/2.5mm (positive pole inside).
This product is ideal if you already have a good photo tripod with a panhead. Otherwise, please go for the complete set: Bresser Montering Set met poolhoogtewig en driepootstatief
