I just came across some data from when I was studying physics... This is a light curve of the eclipsing binary system Y-Leonis published and validated by the American Association of Variable Star Observers. The data was collected with a 0.41m (16") telescope with f/8 Ritchey-Chretien optics on an open fork equatorial mount. There is a Santa Barbara Instrument Group (SBIG) ST-1001E large format, megapixel CCD camera mounted to the telescope via a custom filter wheel. The camera head is thermoelectrically cooled and regulated to operate at a temperature of -40C. I have another lightcurve at the AAVSO. You can generate this curve by entering the Julian date range 2452723.559 - 2452723.875. My observer code is BBD.
