Check for slop by gently pushing the scope in either direction and detect movement before the friction of the clutch is felt.
It may be oscillation due to a loose-ish drive worm/gear contact.

Thanks Jeff,
That is interesting. I'll give it a go next imaging session.
I'm thinking of reinstalling PHD so all the settings I might have changed are changed back to default.
