Flattener Esprit-100ED 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.

Includes:

• Corrector adapter for the ESPRIT apochromat’s M74 mounting thread
• Corrector adapter for the M48 camera mounting thread

The back focus (working distance) from the M48 mounting thread is 55 millimetres. This is ideal for connecting DSLR cameras with a T-Adapter.
