Robin,
It became increasingly tight over time.
From your photos and comparing with the other Lhires the collar looks engaged.
I will overhaul it as you suggest.
Question 1; What lubricant should be used and is there a risk of it getting on the grating?
The remote adjustment is the motorised collimating lens.
Regards,
Jack
