In the Advanced Polaris mount this motor module replaces the manual slow motion control in the right ascension axis. The figure on the right illustrates the modular construction of the mount. The retrofit is therefore very easy and can be reversed at any time. Unlike other mounts with a retrofit right ascension motor, fiddling with more or less compatible motors and gears is not necessary here. Instead, you get a coordinated system from a single source.
The Star Book One is a versatile yet easy-to-use control, which allows tracking in the R.A. and Dec axes with variable speeds. Among the tracking options available are not only the important sidereal tracking, but also speeds for time-lapse recordings and lunar and solar observations. In addition, the control system offers many useful functions, such as backlash compensation, autoguider port, PEC, and a built-in red LED light.
The Star Book One control is intended for, among others, the Vixen Advanced Polaris and SX2 mounts, and is an integral part of the Advanced Polaris R.A. motor module. Please note: if the Advanced Polaris mount is also to be motorised on the declination axis, then the declination motor module is additionally required. In contrast, all motors are already already installed in the SX2 mount.
The motorisation of the right ascension axis is sufficient for tracking the mount during observations or photography. The tracking of the right ascension axis ensures that the movement of the celestial sphere is compensated for.
- Dimension of the Star Book One: 13.7 x 6.5 x 2.1cm
- Weight: 110g
- CPU: 32-bit CISC Processor.
Most important features at a glance:
- The four arrow buttons on the Star Book One directly control the motors.
- The two-line LCD display has an adjustable red background for night-time observation, so that you will not be dazzled and lose your eyes’ dark adaption.
- The menu language is English.
- A variety of tracking speeds are available, in particular the direction of rotation can be changed depending on the hemisphere.
- In order to home in on celestial objects there are four different speeds for you to choose from.
- The backlash compensation ensures that the control is more responsive if the motion direction is changed. This is very welcome when trying to center a celestial object in the eyepiece at high magnification.
- The Star Book One can be used for autoguiding.
- PEC Control: The tracking compensates for the inevitable errors that inevitably occur in each gear. This periodic error correction is important for images requiring long exposure times.
