Nick - Great image showing the discontinuity between the star-like
pseudonucleus and the ever-expanding visible coma.

No joy with 2.0-m images due to bad weather.
However, provided you build the SNR as you have with a longish time-series,
your images can provide data almost as good given suitable seeing and focus.
This becomes increasingly the case as the coma expands because amateurs have
the luxury of sitting on a target for a long time whereas access to the
2.0-m is only for a limited few minutes. At least we got a good result with
the FT South just 19 hours after the outburst started - that's where the
2.0-m really scores well.
