I suspect part of the issue is this is a very specific request, so there will be at best a handful of BAA members in a position to make the observation. A required spectral resolution rather than a specific spectrograph could open it up to a few more observers. Also, when I was doing spectroscopy with an LHIRES III, I would leave it set at H-alpha, so I could be as efficient as possible at acquiring data by requiring only one setup and calibration set.
We do have a spectrum of Europa in the BAA database, but it is low resolution with an R value of 564.

A minor point, but it can be helpful to be more specific in the forum post title. So people visiting the website know a bit more about what you are after without opening the post. Hence, Jeremy’s suggestion to make your enquiry about de-forking your Meade 12″ on a new thread.
Best wishes,
