Hey Stuart nice to see you making progress. Welcome to the world of getting your alignment just right. I found that this can be a trial especially when you tighten down the three outside bolts. I find that the wedge always moves just a little bit. This limits the time down to 3 minutes where the star does not move. Your D70 shots are coming along nicely, just watch your ISO rating. The first shot is sweet but the other two have quite a lot of grain in them. Aside from the obvious tracking errors these shots show real promise. Centaurus A is quite visible and the dust lane is standing out. As for Tarantula, I imagine that you may be feeling the same frustrations that I did when imaged this target.
Anyway, you are well on your way, and the next time you will produce even better results. keep em coming.
