Flattener 1x 2"/M48

The flattener is a lens that evens out the field, as this is slightly curved by the primary optics. This curvature causes stars that are imaged at the edge of the field of view to be less sharp. The flattener, also called a field flattener, corrects this effect. Astrophotographers can then enjoy images where the stars remain sharp right out to the edge of the exposure. The flattener is installed between the telescope and the camera.

The corrector is suitable for refractors from 70 mm aperture to 102 mm aperture. The focal length of the refractor is not changed.

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.

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.
