Overall I think it's still the best LR implementation out there except there are no bell or whistles...
my Arp244 image from last year was improved quite a bit with CCDSharp.
But it is true that decon requires 'oversampling' or at least critical sampling to work properly. What it is doing is sacrificing/trading SNR for spatial resolution, but there needs to be enough pixels per PSF to put that increased resolution into, and of course enough SNR to barter with! Sometimes undersampled images can be upsampled (resized into a larger buffer) and then decon'ed, but I don't think it works as well as imaging at a higher pixel scale since interpolation is added artefacts that can get amplified.
Best,
EB

Cheers Eric, yes I was aware that decon worked better with greater sampling. Wonder if CCD sharp would work with a Starlightxoress camera...?
