What's your field size?
Thanks Marc!
The Classical Cassegrain has a 4.7metre focal length and this gives a field of view of only 26arcmin x 26 arcmin at 0.39 arcsec/pixel unbinned.
Cheers,

I don't think I have seen this one before. Very bright and colourful.

Greg.

Thanks very much Greg!
It's pretty small, but I don't really know why there aren't many images of this one, perhaps imaging with a webcam type of camera, like for a planet might give better results?
Cheers,
