Guide Port for the Telescope Mount

Newer telescopes mounts have conspicuous guide ports where they receive computer input for

autoguiding. They consist of another female RJ-11 modular jack plug that resembles a telephone

modular jack port (Figure 8). One simply plugs the opposite end of the RJ-11 cable into the

modular jack port on the mount and all connections are in place for autoguiding. But there is no

such guide port site on the Compustar. Obviously, the million dollar question is, “Does the

Compustar have some other type of guide port?”

modern telescope mount. One simply inserts the jack on the opposite end of the RJ-11cable

into this guide port to complete the link between the autoguiding computer and the

telescope mount to enable autoguiding. However, the Compustars don’t have such a guide

port.
