Well done Robin. You are showing the way in spectroscopy – as usual!

To avoid any misunderstanding in the light of the current offer on the Alpy it is worth emphasising that you were using a non-standard Alpy which you had modified yourself rather than the one which is supplied by Shelyak. It would be interesting for people here if you could explain the difference in performance you achieved by exchanging the grism.

Thanks,

David
