WO Quality Fit and Finish

  • Precision CNC machined from high-grade aluminum
  • Black anodized finish
  • Brass clamp ring to protect your precious EPs
  • Dual chrome soft screws for secure clamping
  • Internally blackened and grooved to maximize contrast
  • Tapered barrel 2" nosepiece for added security
  • Threaded to accept most standard 2" astronomy filters


  • Total Length = 3.79" (96.3mm)
  • Outside Length of Upper 2" Eyepiece Holder = 2.42" (61.5mm)
  • Length of Lower 2" Nosepiece = 1.37" (34.8mm)
  • Weight = 5.6oz (159g)

Also, note that the adapter can be unscrewed into two separate parts. The two sections are connected by a standard 2" filter thread (M48x0.75). So the lower nosepiece can be used as a 2" 34.8mm spacer ring, and the upper eyepiece holder can be used as an M48 visual back by itself.
