Nice catch Paul....It's a wonderful object.

pretty good first go, might want to look at doing some flats and next time your looking that way capturing photons.

hope that you get a chance real soon to go for longer imaging it.

Good advice from David, also I'd suggest applying some darks to the image too.

Off to a great start Paul, nice star colours there.

Hey Thanks guys for the advice. To be honest with you I am not to happy with the photo. The point mentioned are the reasons why. Yes I needed to add flats to the photo. 2; The camera's dark frame substraction was not enough and I need to add darks and finally longer exposure is the key to extract the last bit of detail.
This photo was really a last thought, I intend to reshoot this object at Heathcote next month with all the above mentioned. Interesting to see if there is a major differences.
Once again thank you for the encouragement.
Paul.

Yep I much prefer applying 'proper' darks rather than using ICNR (in-cam noise reduction).
