I've just had a play with Ken Crawford's positive
constraint Deconvolve tutorial on one of my recent
Star Cluster luminosity results. Open Cluster NGC 2516 in Carina.

Stopping short of doing the multi layer blending
which follows after the deconv/sharpen routine,
I have however improved the sharpness when compared to my
usual routine, which is nearly always too harsh.

1st image is my usual routine which is :

1. crop stack result (remove tracking errors on edges)
2. curves, (I usually use a Keller, QM or DS curve)
3. Sharpen
4. Final histogram adjust, usually set black
5. Noise reduction, usually edge preserving smooth.

2nd image is step 1. but then doing 30 iterations of Positive Constraint
Deconvolution in CCDStack before steps 2-5.

3rd image is a more aggressive 150 iterations of P.C. Deconvolve then
steps 2-5.

I have hardly ever used a deconvolution routine before sharpening on
Deep Sky stuff and am kicking myself! Quite excited though at the
prospect of repro-ing some of my better DSI II results.
