TELESCOPE TUBE COLLAR

 

This is an aluminum tube collar built for an astronomical telescope tube assembly.

Inner diameter of ring is 9 1/2", length is 6" with threaded holes for retaining screws.

Axles have been block-welded to the outer ring surface at a precise 180 degrees.

Axle ends turned down to 1 1/8" diameter; 21" end-to-end.

One axle has a clutched gear for a declination slow motion mechanism.

Gear is 6 3/8" diameter, 98 tooth.

 

This collar would undoubtedly work with an 8" OTA depending on the outer diameter of the tube.

Measure to be sure. The I.D. of  this collar is exactly 9 1/2" (242mm.)!
