follow-up observations on 28 dec.2017 from BRIXIIS Kruibeke

After more than 4 weeks of cloudy weather, i could made some follow-up images of comets: 47P, C/2016 R2C/2017 O1 and C/2017T1.  There were only some small periods of clear sky, only very late (after 1:00 u) there were more periods of clear skies.  Images can you find in the links of the cometnames.
