Comet C / 2017T2 observed from the Frasso Sabino observatory ( Cassegrain 369mm in diameter and 2464mm focal length ) the night between November 30th and December 1st. The average time is 22h29m13s UT and they are 24x90s. Average in groups of 3 and then add up. Unfortunately the sky was not good and sometimes veiled. In the elaboration I rescaled in logarithmic way and applied a DDP filter. |
