Thanks Barry, you nailed it, the comet is clearly visible centre frame.

I used 4 programs to plot the position; The Sky X Pro, Starry Night Pro 8, Sky Safari and SkyTools 4 and all of them indicated positions several degrees apart.

I made sure that I refreshed all the Comet Elements for each program via downloads and checked that my observing site and details were all the same and correct, so not sure why the variation - I suspect they must use different sources?

Cheers

Dennis
