1. NGC5189 is very small and dim - as you can see from the full (unprocessed) frame - making it a tricky subject for OSC imaging with modest gear like mine. This is possibly why there are so few examples of this object here on IIS
2. Imaging at 0.9 arcsec per pixel clearly requires good seeing, especially for such a small target
3. The detail in Mike's image (giving the seeing and tracking limitations of working at this image scale) is simply incredible
I am surprised at your description of NGC5189 as faint
I find it is one of the brighter PNe's
Maybe it's my dark sky and large scope which has me confused
Cheers
