The current for the two stepper motors is sine wave shaped. This means that the motors run very silent, with no vibrations and with a very steady torque. This is called microstep mode.
5 programmable slewing speeds up to 3200x, for example 1/4x, 1x, 5x, 20x, 60x or: 0.3x, 1x, 3x, 10x, 500x. The maximum available speed depends on your motors and gears.
The tracking speed can be selected for:
- Stars, Moon, Sun
- Comets (both axes are programmable, King Rate is possible too)
- Earth (no tracking at all, e.g. for adjusting the optics)
Automatic Slewing to Objects (GoTo)
- All 109 Messier objects
- A practical selection (>3500) NGC and IC objects
- 168 bright stars (all stars brighter than 3rd mag)
- Sun and planets
- RA and DE
- If you didn´t find yout object right away: Automatic searching on a spiral-shaped track around the center of the field.
The normal version needs a 12 Volts (±3 Volts) DC supply. All versions are protected if the supply is connected the wrong way round, they have a built-in fuse and a 1 Meter power supply cable with banana plugs. As a power supply we recommend a 12 Volts car battery or a 13.8 Volts DC regulated power supply.
Please don´t use unregulated power supplies, because the output voltage of these can be higher than 15 Volts if the load is small.
