<p class="MsoNormal" style="margin-left:.5in">Hello Anders,<br>
<br>
I don't know what your expectations as to how sharp the image should be are, but your data set is too coarse to obtain a sharper rendering. What I suggest is that you either refine your mesh or you resample your data onto a finer vti image and then do the volume
rendering. I have attached a picture with your original galaxy and a resampled one, perhaps this is what you are looking for. I must admit though, that the left image looks more "Hubble-like" :-).<br>

You could also try contouring it at different levels, and turning opacity to ~0.5 or so.<br>
