Greg,

Yes thanks for that Allan. I am pretty sure.
I'd have to check the workflow but the initial processing I always do is using CCDStack and I think default is 32bits but perhaps its 16.
It may be something I need to check in CCDstack to default to 32.
Repro posted to the same links.
Thanks for the feedback.
Greg.

Hi Greg,
the repro is much better & I'd be interested to know if it was stretched in 32 bits?
The bright areas are in a narrow range - & so are the dark areas.
It still looks like those areas could be stretched out.
I have found that
FITS Liberator does the hard work for you
when used in compression mode & it's free from NASA.
I have used it in compression mode x^1/5 but your image might
work better in x^1/3 or one of many other functions.
It can then be saved as a 16 bit TIFF for processing in Photoshop
or just about any other package.
Also - I don't know whether all the blue on the left hand side is real or not - it could be a partial blue caste.
I wish I had such lovely data to work from.
I've had 5 months of cloudy weather in Melbourne.
cheers
Allan
