On October 16th, using the 2.56m Nordic Optical Telescope at La Palma Spain, the observations of the Kepler candidate KOI-0401.01 were conducted by the students. In addition to a standard broadband photometric filter, one of the two brand new holographic diffusers was used, with the main purpose to increase the photometric precision of the transit event. Besides the field trip to La Palma, the students had theory lessions during the autumn and field practice using a 0.5m telescope in Norway. From the data analysis, at a one-minute cadence an outstanding photometric precision of 0.85 parts per thousand was reached. Considering KOI-0401.01 is a 15 magnitude star, these first results from the diffuser are pretty neat!
