Telescope Field Flatteners

 
 

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 depends 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!

For example, the Starizona Apex ED 0.65x Focal Reducer & Field Flattener works with apochromatic refractors as well as Ritchey-Chretien and Meade Advanced Coma Free telescopes. Besides reducing the focal length by 0.65x, it also eliminates chromatic aberration and produces sharp star images over a 30mm circle.

Own a Tele Vue scope? The Tele Vue Large Field Flattener for Tele Vue 101 or 127 IS Telescopes is designed for Tele Vue NP101is and Tele Vue NP127is telescopes and is recommended for use with 35mm and larger CCB sensors.
