500 grams. Especially designed for f3 to f8 systems. Excellent Condition.

Accurate  fine focus is achieved by means of multiple precise helical threads.  The Helical Focusing Range is 10mm. which works well with parfocal eyepieces. In addition it also uses the manufacturer's sturdy Draw Tube with its retainer Collar.

This focuser was used for only  about a week or less.  Focuser has been stored unused in a closed carton since the early '90's.  Because of challenging health issues I cannot actively observe anymore and am in the process of selling off my equipment and accessories acquired over many years doing ATM and visual Deep-sky astronomy. 

This wonderfully engineered professional piece of CLAVE equipment was supplied byLes Appareils De Precision - per  Kinoptik Purchase Order Feb 13, 1989 which I purchased from Roger Tuthill, Mountainside, N.J. March 6, 1989  
I paid a total $554 for these items.

This may appeal to enthusiasts of  Clave and related fine equipment for this famous marque. 

Asking $390. Reasonable offers considered.  Shipping negotiable. Will be very carefully packed. 
Payment by International bank to bank wire transfer. Eyepiece not included.
