RE: [APML] OT: Lunar Mosaic

Hello Juan,
That is big and sharp.  I have a question.  What (in simple terms) is the
difference between Photoshop sharpening/unsharp mask and deconvolution in
other programs?  Thanks.

The camera is a Philips ToUCam Pro and the scope a Meade LX200 12"
Schmidt-Cassegrain at prime focus (f/10). Each image is the integration of
300 to 500 video frames captured, selected, aligned and averaged with
K3CCDTools. The mosaic was constructed in Photoshop 6. Finally, we applied
12 iterations of the Van Cittert deconvolution algorithm with a gaussian
function of radius 2.0 taken as the PSF (own software). The above image has
been reduced to 3500 pixels wide and weights 1.2 MB.

Here is the image prior deconvolution:
