SkyWatcher Field Flattener Corrector for Esprit 80ED and 80EDX

SkyWatcher Field Flattener corrector for Esprit 80ED

Turn your SkyWatcher Esprit 80ED f/5 apochromatic SkyWatcher telescope into a high-performance astrograph with this specially designed Field Flattener. This accessory eliminates the field curvature characteristic of refractor telescopes, providing sharp, focused images right to the edges even with large-format sensors.

Thanks to its correction and uniform illumination up to 42 mm in diameter, the corrector allows you to work with astronomical, DSLR or full-frame mirrorless cameras without vignetting or loss of quality in the corners.

The working distance of 55 mm from the M48 thread to the sensor ensures easy adaptation using standard T-ring adapters (such as SKM-... for DSLR cameras). In addition, the adapter design allows threading 2" filters (M48x0.75 thread) without altering the focusing distance, facilitating the use of narrow band, LRGB or UV/IR-cut filters directly at the camera connection.

On the telescope side, the corrector is connected via an M74x1 female thread, ensuring a tight and perfectly aligned connection to the Esprit 80ED focuser.

Manufactured with high quality, multi-coated optics, the SkyWatcher Field Flattener offers excellent light transmission, high contrast and the optical reliability that characterizes the Esprit series.
