Troy,
I've been using ATWT and MMT for a while for both noise reduction and sharpening. I don't think they replace deconvolution but they can certainly be used to enhance the image afterwards. Deconvolution attempts to reverse the blurring due to seeing and other effects using an estimated point spread function. This can actually reduce star sizes and recover details. ATWT and MMT just enhance what is already there.
Cheers,
Rick.
