Old WO refractor focuser.....

[dweller25]

Hello,

Does anyone know the difference between the old and new William Optics Crayford focusers for refractors ??

Did they have problems with the old one ???

Well, for a start, different WO scopes had different focusers!

The focuser on my WO FLT 110 is fine. No issues ... a little coarse for my taste (even using the reduction gear) but really smooth, big range of adjustment, no vignetting & I haven't managed to make it slip.

Yes, fair comment.

I meant the replacement focuser for Synta refractors.......

The one currently sold is an improved version - what did they improve and why ??
