Alun,

Thanks for the link, some good modifications.

I can put one cover back on once I have got the belt gripping properly, will try putting o rings over the lens thread.

The Lhires is contained in a film changing bag which should keep dust and light out. 

A question, as I do not operate the spectrograph remotely is there any point in motorising the micrometer arm ?

Regards,

Jack
