Hi Clive,
Ok my summary.....
non crunchy stars......

color balance ok (?) i think so.......

histogram not clipped , sky value 20-30 .......

(I like it about 25-30 myself)
detail in the nebulosity.......

Excellent!
Very nice image in every respect. Nice color balance stars are nice and natural looking and heaps of detail in the neb itself..The detail in the neb its self is really amazing, even the very brightest parts show that lovely mottled texture which you have brought out really well...I think this is when your new camera with its full dynamic range really helps!
More please...
