Thanks Paul. Pleased you liked it. Narrowband has an artistic flavour to it.

I guess its about perception Clive. The OIII data has caused some areas to be higher in illumination than others. The flat corrected most of it but with an F/3.6 optical system flats can be erroneous. The top of the image I believe is accurate, but perhaps too light. Actually, to the top is NGC7822 so there is certainly nebulosity present there. I just didn't expect there to be much OIII. Appreciate your feedback and honesty.

Thanks guys

Cheers
