Fantastic result from an ED80 and a webcam. Great detail.

Also, if you software supports it, view the histograms in your capture software before capturing, and adjust the RGB histograms until they are all roughly equal, it will save you some time in post processing if you can get the colour balance adjusted before you capture.
Really though, these images are great. Go a bit longer, up to 2 minutes for each capture, a bit of deconvolution or wavelet work, and a colour tweak and they will look fantastic.
