     This Small Compression Ring Set from Novagrade includes four compression rings and permits any Novagrade digiscoping adapter to be used with 23mm to 40mm-diameter eyepieces. Such eyepieces may be found on microscopes, small telescopes, and binoculars. 
 
 Installation of any of the compression rings within this set can be accomplished by first unscrewing the retaining ring on a Novagrade digiscoping adapter. The adapter's existing compression ring can then be removed, allowing one of the four included compression rings to take its place before the retaining ring is returned to its original position. 
 
 The included compression rings each feature an expandable design and allow a Novagrade digiscoping adapter to maintain a reliable fit on eyepieces with diameters that fall within the following ranges: 
 
 23 to 28mm 
 27 to 32mm 
 21 to 36mm 
 35 to 40mm 
 
 Each compression ring is constructed from an injection-molded plastic polymer and is made in the USA.
