  Time series photometry of 20 Cataclysmic Variables detected by the Catalina
Real-time Transient Survey is presented. 14 of these systems have not been
observed previously and only two have been examined in-depth. From the
observations we determined 12 new orbital periods and independently found a
further two. Eight of the CVs are eclipsing systems, five of which have eclipse
depths of more than 0.9 mag. Included in the sample are six SU UMa systems
(three of which show superhumps in our photometry), a polar (SSS1944-42) and
one system (CSS1417-18) that displays an abnormally fast decline from outburst.
