Sharpening of Astro-Images

Hi Charles,
I normally use CCDSharp (from SBig) or the unsharp mask functions in
Photoshop or combinations of both. Some images come out quite well after
sharpening, others do not ! It's a case of experimenting with each image and
trying not to over do it.
Cheers
Dave

Hi Everyone:

Thank you to those who answered my previous query!

I now have a question regarding the sharpening of astro-images. I have
tried
a couple of ways to sharpen my astro-images (PhotoShop, Maxim DL), but
they
all look artificial to me. Some nebulae look indistinct by their very
nature
(gas clouds). I have an image of the Rosette Nebula which I would just
like
to sharpen a bit without impacting on the natural look of this object.
Does
anyone know of a way to do this? My files are large 60 meg Tifs, so I am
able to get real close and check the results, but even if it is smaller
scale (just filling my monitor) I can still tell if it looks "artificial".
Perhaps I am being naive, and any sharpening tool will be unacceptable.
Any
help would be appreciated,

Thanks,

-Charles
