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.
