FIELD FLATTENERS & REDUCERS

(87 products)

We stock a range of field flatteners & reduces for refractors and Newtonian telescopes, including the dedicated flattener/reducers for the SkyWatcher Evostar series and Sharpstar/Askar apochromatic refractors, as well as Sharpstar & Baader MPCC multi-purpose come correctors for Newtonians.

Field flatteners/reducers are essential accessories for reducing the field curvature, chromatic aberration and coma inherent in many optical designs. For visual astronomy, these issues are not as important, but if you want to do deep sky astrophotography, you'll need a flat field. Be sure to select the appropriate flattener/reducer for your particular telescope.
