GCVS?

Have you downloaded the complete GCVS?  If so a preliminary selection based on a minimum Dec, a plausible range of RA and a type of EA, EB, … will give you an initial range of candidates.

What do you consider high-cadence? Minutes, seconds or milliseconds?

My 0.4m telescope (located only about 100km from El Teide) could manage a very few millimags precision (unfiltered CCD, so approximately Gaia G band) down to mag 11.5 with a cadence of around a minute as demonstrated with an observation of an exoplanet transit.

In fact, why don’t you try for an exoplanet transit?  Not only do you get your differential timing data, you also add to our knowedge of exoplanets.  The minimum may be wide but the ingress and egress events are short-lived and it’s generally possible to observe both in a single session.

Would you like me to join in perhaps, weather permitting?  It’s been unusually cloudy in these parts of late.  I also need to get the new camera commissioned first but I hope that doesn’t take too long.
