1.0x-Corrector and Field Flattener for Refracting Telescopes

The corrector is suitable for ED, apochromatic or achromatic refractors from 70 mm aperture to 102 mm aperture. It corrects the error at the edge and thus allows astrophotography through the telescope. The stars are imaged pinpoint up to the edge. The focal length of the refractor is not changed.

Connection of DSLR, system cameras or astro cameras

The optimal distance from the M48 thread to the sensor of the camera is 55 mm. To connect an SLR camera, you only need an M48 adapter ring. For system cameras or astro cameras we offer suitable adaptations.

Connection to telescope

The corrector has a 2" barrel at the telescope side. With this, the connection to the telescope is possible without any problems. Every refractor up to 102 mm aperture, which is designed for 2" accessories, can work with this corrector without problems. A filter thread for 2" filters is available at the end of the barrel.
