We demonstrate how a small, robotically controlled telescope can be used to monitor bright, long-period variable stars in dense stellar systems like Galactic globular clusters. Observations of NGC 1851 gathered with the No. 5 PROMPT 0.4 m telescope in yielded quality color-magnitude diagrams to well below the horizontal branch at. We recovered many of the known RR Lyrae variables, clarified the nature of the three known bright variables in the cluster, detected two new long-period variables, and flagged seven more suspected variables. We describe methods that should yield good results in variable star searches and monitoring using this and other small telescopes.
