This complete set includes everything you need to track a camera with night sky photo lens . So you succeed in long-time-exposed shots of large star fields and other atmospheric sky photographs - and surprisingly easy!
The core of the photomontage is a stepper motor that compensates for the sky rotation by rotating the axis of the mount (called the "hourly axis") at the speed of the stars ("sideral"), keeping the camera aligned with the desired sky.
For this to succeed, the photomontage must be sorted: Just aim with the integrated polar finder the Polarstern and already 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 put all cameras with the usual photo thread (1/4 "and 3/8") and align it to the desired sky area.
The camera also requires only a setting for long exposures and of course a lens. Typical achievable exposure times with good tracking accuracy are: 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 ("tracking") at different focal lengths.
Battery operated: Included in delivery is a small bag for holding the batteries. Optionally, a power supply can be connected: 6V, DC socket 5.5 / 2.5mm (positive pole inside).
The height-adjustable stainless steel tripod is ideal for the Bresser photomontage, because it has a so-called pile height cradle . The mount can be fixed to the cradle with a 1/4 "thread screw, which can then be precisely aligned with the pole star due to the fine adjustment of the azimuth and latitude (pole height) .If the pole star is not visible, this is also possible at least for short exposure times on the height scale and an optional compass.
The pole height and the azimuth are adjusted by large knurled and thumbscrews . The integrated tripod head in circular level, the leveling of the tripod is a snap.
