Explore Scientific FE02-020 Features
- More Magnification Choices without Sacrificing Eye Relief: A good Focal Extender adds some real versatility to your telescope accessory line-up. First of all, it allows you to increase the magnification of any eyepiece with the same barrel size that you already own
- Optimized Optical Design: Explore Focal Extenders are optimized through each design, fabrication and testing process to produce high contrast, high resolution images
- Durable Coatings & Finishing Touches: Each of the four elements in your Explore Scientific Focal Extender is fully multi-coated with EMD enhanced coatings, resulting in bright, sharp images; and every element has blackened edges to reduce internal reflections and increase contrast
- The insert barrel of each extender is double-tapered to allow smooth insertion to and removal from a telescope's eyepiece holder, focuser or diagonal, however dimension of the taper helps prevent the focal extender from falling out of telescope should the set-screw holding it in place become loose
