Thanks gents...It's such a small nebula. and it's a learning curve.
Needs more subs but for this object it's probably late in the season as it heads towards Melbourne's sky glow from around 11pm onwards.
Also the atmosphere at the time was crappy..at best. But after around a month of clouds...I'd cut out a magazine photograph and take pictures of that!
A 2nd go at curves & levels has revealed a lot more data than the original..but noise & background is all wrong. I may try layer masking...if I knew how.
