Lumicon Richfield Viewer for Threaded 7-9" Schmidt-Cassegrain's

The Lumicon thread-on focal reducing lens takes your Schmidt-Cassegrain's f/10 optics and reduces them to f/6.3 for beautiful wide-field views and brighter object images. The fully-coated Lumicon Rich-Field Viewer lens has a larger clear aperture and less coma than higher priced focal reducers on the market, providing superb unvignetted views.

Its 2" inside diameter allows you to use The Lumicon Rich Field Viewer with your Lumicon 2" Enhanced Aluminum Diagonal. Included is an an aluminum 2"-1.25" eyepiece reducer (threaded for use with your Lumicon 48mm filters), allowing you to use 1.25" eyepieces together with your Lumicon 48mm Light Pollution Block Filters.
