Alex those are awesome sketches!
And thanks for your report- both are a fabulous contribution on here.
I haven't been able to see the tail yet as cloud has ruined those chances these past few days, but I've been able to throw binos on it between quick gaps. Hubby & I could see there was some sort of colour thru the binos. It didn't look the typical grey that a view normally is, I don't know quite how to describe it but I'd lean towards a dark bluey/grey (just! if you looked hard enough). I could see a teeny elongation a week ago (observing thru my 10" dob) so next time I'll have to try looking harder for a tail as hopefully it'll be a bit brighter then when next I observe it.
