Re: [APML] NGC6820 - a CCD attempt to emulate Film

Hi Mike,

this is a superb image! Iīve not seen such a composit of hII and RGB images
with ccd yet.

Itīs fantastic to see the different colors of the stars and the smoothness
given from the ccd.

Did you hold the colors with the process in PW 2.5 you describe on your
homepage?
