The guiding looks to be much better. What size and what format is the image from your system? I had a shot at using gradient exterminator and a bit of Richardson Lucy enhancement, This would work far better on the original. The detail is there.
Its strange that you call it Richardson Lucy, all us planetary images know her as Lucy Richardson in Astra image. Wonder if it does the same thing. Is it a deconvolution that is done once you split the colour into red, green and blue channels?
