I have imaged this delightful object a couple of times. Once from Ten Chain Hill in 2011 and again from SRO in California in 2014. Both my attempts at processing the data were pretty woeful though I thought them OK at the time. Hopefully, I have finally done the combined data more justice this time and won't have regrets in 2017
