Function and Use<\/h3>\n

The 0.85\u00d7-L Multi Reducer widens the FC-76D\u2019s field of view by reducing the focal length to 486 mm at an F\/D ratio of 6.4. Its four elements in three groups correct the field of view to a 44 mm image circle, compatible with the full-frame format. This configuration is suitable for wide-angle subjects that require a wider field of view than the native focal length provides.<\/p>\n

Compatibility and Installation<\/h3>\n

The L version includes the reducer and its dedicated CA ring. It mounts on the FC-76DCU, FC-76DP, and FC-76DS. The fittings upstream of the reducer vary depending on the telescope\u2019s eyepiece holder. On the camera side, the included CA ring features an M52 \u00d7 0.75 thread and accommodates the camera adapter ring suitable for the camera body, according to the Takahashi diagram.<\/p>\n
