very nice ... billions of stars and liking the 'milky' nebulosity... for 30 secs amazing - John

[RobertM]

Thanks John.  I definitely overdid the colour somewhere so I'm going to redo colour balance using the G2V method and see what happens.

Marvelous

Brilliant.

[RobertM]

Ok, this is the G2V calibrated version.  Much happier with this though it still has many warts including a nasty dust bunny.

Really like the latest calibrated version, the colours are better and it's got a sort of hazy glow in places.

Thanks all.

Thanks Carole.
I believe there is some faint reflection nebula in the area so maybe that's the hazy glow.

That's looking excellent Robert - though I'm unable to see it full size because ADSL performance at Virgin Media is dire at the moment - some ongoing server issue apparently.  It took 5 attempts just to see the versions you posted inline in the thread.

The G2V calibrated version looks the best but I would have been tempted to boost the saturation a bit.

Thanks Mark, saturation is something I still need to get to grips with.

Hope your broadband gets sorted quickly.
