Have to say I was slightly underwhelmed at T2 on the evening of Jan 20. Although overhead, the background sky is always too bright to appreciate Comets from Birmingham, even fairly bright ones like this. In the 51cm with a 10mm Ethos I could just discern the tail. Ten minutes later, and a degree or so away across the open cluster, I was seeing close to mag 16 in a variable star field with the same eyepiece. My first Comet was Bennett in 1970, and I have loved observing them ever since. However light pollution has virtually ended this aspect of visual observing enjoyment for me.
