Product Description

The 18mm CEMAX eyepiece was designed to optimize hydrogen alpha solar viewing. To fit the full disk of the Sun into the eyepiece field, this eyepiece should be used with a telescope focal length of 1500mm or less.

For higher image contrast, a soft rubber eyecup shields the unaided eye from ambient light when extended. The eyecup folds down for eyeglass use. There is a safety groove cut into the 1.25" chrome barrel. This engages the thumbscrew of the focuser to prevent the eyepiece from falling accidentally should the thumbscrew loosen during use in the heat of the day. Plastic dust caps are provided for both ends of the eyepiece. A rubber grip ring around the brass-colored body provides a sure grip in hot weather.

This eyepieces is NOT a hydrogen alpha solar filter and MUST be used in conjunction with a separate hydrogen alpha solar filter to avoid the possibility of instant and permanent eye damage!
