Three fine DSLR images there Richard, congratulations, The M83 is great.
Great scope too, Guy is a talented individual who has made some pretty cool scope stuff over the years
BTW, I am surprised you haven't had more comment about your deep Cen A image
..perhaps it is my fault, I may have bored everyone because I posted so many versions and repro's during 2008/9 and that image was seen so often in so many places that everybody is sick of that galaxy now..or perhaps just the mention of my name did it
If so I apologise
Mike
