SkyWatcher Field Flattener Corrector for Esprit 150ED and 150EDX
SkyWatcher Field Flattener corrector for Esprit 150ED
Turn your SkyWatcher Esprit 150ED f/7 apochromatic SkyWatcher telescope into a high-performance professional astrograph with this specifically designed Field Flattener. This optical accessory eliminates the telescope's natural field curvature, providing sharp, in-focus images right to the edges even with full-format sensors.
Thanks to its correction and uniform illumination up to 42 mm in diameter, the corrector ensures exceptional results in deep-sky astrophotography with CCD/CMOS, DSLR or mirrorless astronomical cameras. The design maintains the original focal length of the Esprit 150ED, preserving the f/7 focal ratio and its excellent light gathering capability.
The corrector features a female M74x1 thread for direct connection to the telescope focuser, and a male M48x0.75 thread (2" filter thread) on the camera side, allowing for easy attachment of standard filters without changing the focusing distance. The 55mm working distance ensures a perfect fit with common T-rings and adapters for DSLR or astronomical cameras.
Built with precision optics and multi-coated optics, this SkyWatcher Field Flattener guarantees optimum light transmission, high contrast and flawless stellar reproduction right to the edge of the field.
