Beautiful David! The optical quality of Bunyip never ceases to amaze me and this is very nicely processed! Normally I'd say you need more FL for this object (which would be nice of course - just ask Fred), but you pulled it off thanks to those optics! Even the two tiny, distant galaxies off to the right show good detail. Well done!
It would be interesting to know what spot sizes you're getting at the edge of the field.
Cheers, Marcus
