  • While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending off to the factory is an option, but is not required.

  • The heavy-duty 2" diagonal has 99% dielectric coatings for high contrast, bright images. A 1.25" compression ring adapter is included.
