As I comment on the page, there isn't much variation in star colour captured whic is perhaps a negative, and there's the wonderful distortins I'm battling with the WO FFv3, but the overall golden dusty, sparkling look of the stars/image I really like for some reason
I'm not sure ... maybe it's poorly processed and if processed properly it would have more colour? more variation? MabyeI haven't got the white balance right and it's too yellow, I don't know for sure but I'm reasonably confident I've got the coour true to what I captured on the night
Stunning amount of detail. Cripes, one of the dust features immediately to the right of the centre of M7 looks like a winged man!
M7 too is one of my favourite clusters. As a youngester, I only could see, and knew of, only the main stars forming this naked eye cluster. Didn't give it too much telescopic attention since until a chart available through IIS showed that M7 is a 4 for the price of one special, with another open cluster (seen here to the bottom right of M7- 'smaller' stars, more densly compacted cluster), a planetary nebula (too small to be seen at this scale), and a faint, small globular cluster (washed out, and probably to small also to make out clearly).
I'm still to find the planetary, but the globular is a little challenging to make out through the glare and confusion of all the bright main cluster stars.
Not doing imaging, I do have a question about the iso speed selected. Of cause this ain't film, but how would a slower speed setting affect the picture, other than making for a slower exposure. I wonder if the speed settings would not affect the colour rendition of the camera somehow. Might there be a colour imbalance occuring at this iso setting somewhere in the hardware?
Similar to my field from a few weeks ago, through the ED127.
I think you have a bit too much red there, Roger. Try easing back on the red and perhaps introduce a bit of green.

Thanks H .. seems obvious now. I've updated the image to a new less red one, tweaked the green too. I think it's better without a doubt. Thanks!

Interesting to hear about the Planetary ... I'll have to look at my 100% size image just in case
Good question about the ISO. I chose 1600 because it was a cold night so wasn't too worried about noise (noise being the biggest problem of higher ISO) and in the end I'm glad I chose the higher ISO because noise really wasn't a problem in this particular night.
As for colour I think there is a variation between ISO's on colour balance. I think there have been other people in IIS which have done some ISO tests in recent times and shown a difference in colour, I think that was tested ISO 400 vs 800 but sure 1600 would show a variance too. Interestingly you don't notice it in short "terrestrial"/"normal" photographs (or I haven't at least) but in the long exposure the ISO does seem to have an impact on the colour balance. Perhaps it's that which made my original image redder
Gettin' there. I reckon you can push it a bit further, too.
I found two green blobs with a red middle in my version and I thought it was random noise so cloned them both out. I found out later on that they were planetary nebulas, haha!
