These quality field flatteners from High Point Scientific create wide, flat viewing fields for stargazing. When your scope is sharply focused, you may notice stars and other celestial objects at the edge of your field of view to appear blurry or unfocused. A field flattener corrects this problem. They reduce the normal field curvature inherent in most refractors. The result is an image that is sharply focused out to the very corners of your field of view. A field flattener is also must-have for observers interested in astrophotography. This way your images are sharp and clear without any distortions at the edges.


We offer a full line of field flatteners for you to choose from. We carry field flatteners from virtually all major brands, including Celestron, Stellarvue, Meade, William Optics, Orion as well as many others. Many can be used with either a CCD or DSLR camera with the correct t-ring installed. However, when using a field flattener with a CCD camera, you may need extension tubes or spacer rings to achieve the necessary backfocus. This is because the backfocus of CCD cameras depend on the model.


Not all field flatteners are created equal. Oftentimes, a field flattener also has focal reducer capabilities, so you can get wider shots out of your scope. Be sure to check each field flattener we carry to see if you can use it as a focal reducer as well. Field flatteners also come in many different sizes, sometimes designed for a specific telescope model. If you’re unsure what to get for your scope, the experts at High Point Scientific are standing by to help!
