SKU: MEA-07545

Meade Series 4000 f/6.3 Focal Reducer

Threaded on to the telescope's rear cell, the f/6.3 Focal Reducer/Field Flattener reduces the main telescope's focal ratio by a factor of 0.63 (e.g. from f/10 to f/6.3). It can be used for visual work when the user desires a wider field of view, or when placed in front of a CCD imager, #62 T-Adapter or Off-Axis Guider and camera body, the f/6.3 reducer produces photographic exposure times by about 50%. Designed primarily for f/10 and f/15 LX-series model telescopes, the Focal Reducer can also be used photographically and in CCD imaging applications with f/6.3 SCT's, resulting in an effective focal ratio of f/4.

Meade Series 4000 f/6.3 Focal Reducer Features:

  • The Meade focal reducer screws onto the rear cell of SCT's, converting f/10 scopes to f/6.3 or f/6.3 scopes to f/4

  • Reduces photographic exposure times by approximately 50%
