Very sharp image Colin.

Trish and I seem to be in the minority in much preferring the HSO palette, but this is a fine rendition.

I think you're saying you remove the stars, deconvolve the starless image, and then put the stars back. Two questions:

(1) Why not deconvolve with the stars in? Is it to avoid panda-eyes around the stars? We certainly do wavelet sharpening on the starless image, for that very reason, but with deconvolution we use an anti-panda algorithm.

(2) What do you use for a point spread function if you are deconvolving the starless image? Do you load the PSF from the with-stars version, or do you use a synthetic PSF?

Best,
Mike
