A stunning and unique looking image, Paul.

Great nebulosity and amazing detail.

What focal length was this working at? It appears to be quite hi-res.

Thanks IceMan,

The effective photographic focal length is about 1875mm. Also you are only seeing a cropped portion of the entire image, which was then divided by 2 to get the image size we see now.
