All Pictor CCD models plug in directly to the control panel jacks of Meade LX50 and LX200 telescopes or to other telescope brands with similar autoguider ports. Telescopes with separate, retrofitted drive correctors may be used with any Pictor model by means of the 520 Electronic Relay. The 520, a microelectronic device without internal moving parts, consists of a small (cigarette-pack-size) box with telephone jack input on one side and connectors for a wide range of drive corrector directional controls on the other.
