Ok I will chime in here, like any sharpening tool you can use it like a surgeon's knife or a blacksmith's hammer!
To remove the "blur" from the data we get is not perfect but it can make a huge difference. Not all Decons are alike of course and some really add noise to the background, black ring stars, ect. I have found that I use 3 different sharpening methods on the same image.
(1) Multi Strength Decons blended with layers using Positive constraint for the high signal details. This is done in CCDStack2 Then brought into PSCS4 for blending. This way I can use a mild Decon to tighten the stars and the small faint fuzzies and a hard decon on for small details in the object and blend them together. This way I leave out the noise and the damaged stars.
(2) I will use different layers of High Pass filters with different blending modes so it works kind of like a wavelet filter. I use masks to blend in where I want it and to also stay away from the stars. I use a brush on the mask for precise control.
(3) I will then work on the tiny little details with a decon PS plugin called FocusMagic. This is used with a mask very carefully and selectively.
Then finishing off with blending modes like softlight and color dodge you can use color and contrast to make things pop and look sharper.
I am working hard on AIC2010 right now but will produce another tutorial to demonstrate putting all of that together if anyone would be interested.
Kindest Regards,
