Julian,
Great write-up, well done!
It shows the capability of the grating very well....
A survey of the southern sky to identify all the "emission" stars (Be/ WR) would be a good idea (I have an objective prism set-up ready for such a task - pity to doesn't work through cloud!)
It is very satisfying to be able to record, see a different spectrum profile, and then identify the star.
Great stuff.
