Fancy a tweak anybody?

Here's a link to my latest D40 image of M13 warts and all.

I switched the colour off to post eleswhere but wondered if

somebody might fancy a more technical go at orange removal.

The image was ISO 800 for 75 seconds.

Exif says 88 seconds but that included the time taken with a shield

up front for a few seconds into the exposure to allow things to settle

after the mirror clunked over

File is 2 Meg ish...

Here's my effort. A bit of curves stretching in PS and balanced the orange bias using individual colour channels in levels. Russ Cromans gradient exterminator for the small amount of vignetting. Bit of selective sharpening with unsharp mask. A few colour balance adjustments. Superb image Philip

Thanks for that Martin

Looks better with some colour back in (other than orange)

Bought the astro tools for Elements that you suggested..

Going to have a learning session later
