Yep Paul, an article would be wonderful.
I use StarTarg, but have just downloaded and run K3. The drift tool looks promising and I'm keen to give it a go. I always have a problem with StarTarg when asked to find the northern side of the scope by "flashing a red light from the north". Silly way to write instructions from one of the best in the instruction-writing game IMHO. What if you're using an SCT with diagonal, or a straight-through refractor?
