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.
