Green Witch Focal Reducer/Field Flattener

f/6.3 Focal Reducer/Field Flattener Ref: MEA-07545

MEADE The f/6.3 focal reducer/field flattener is an important aid for the astrophotographer using an SCT. It threads onto the rear cell of the SCT changing an f/10 optical system to f/6.3. The wider field of view is especially useful when working with CCD cameras with small detectors, and the lower magnification relaxes the drive and guiding requirements. The flatter field it produces also improves image quality at the edges of the field of view. The f/6.3 focal reducer enables photographic exposures to be shortened by about 50%.

MEADE For ultra-fast CCD imaging the Series 4000 f/3.3 Focal Reducer/Field Flattener converts an f/10 telescope to f/3.3 and an f/6.3 telescope to f/2. Improved colour correction and better edge-of-field performance are also provided. Please note that the f/3.3 unit is not recommended for visual or photographic imaging applications.
