Af(rho) data, obtained from images taken as described for CARA approuch (filtered images with R and/or I Bessel filter)

The evening of 2 april was a clear night, I made my setup of a DDM85 mount with ED80 refractor and ST10XME camera with R-Schuler photometric filter. After some search in the sky I could found the comet. This comet was very low on the horizon. I could take about 35 images of 40 sec. Exposuretime with R-Bessel filter in a 1x1 Binning.
