Yes the NPC looked quite interesting and different from the previous apparition. Another month and it will most likely be just a small white spot with little if any detail.

Dan this is a processing artifact. I will need to reprocess this side of the planet and remove the edge artifact as it is called. The estimator is the likely cause for this artifact. I will need to do two processes one for the edge and one for the surface detail and then do a layer mask to combine them.
Skies at Clayton are superior by a very large maring to Victor Harbor. The skies are very dark at around 21.5-21.6 on an SQM. There is some light spill from Adelaide (around one and bit fists up from the horizon) and some lighten in the sky from Goolwa. Other than that my DSO imaging results (see my website) pretty much show what the skies are like. 5 street lights in the whole township that are turned on and the rest have been disconnected (nearly 30 lights). Nice bylaw made by an understanding council.
Seeing as I said is superb most of the time, I have only ever seen one night where the seeing would have been poor. All other times the seeing has been around 6 and up.
