Takahashi Extender for the Epsilon 180-ED Telescope!
Take your Takahashi Epsilon astrograph to the next level with the dedicated 1.5X Extender, designed specifically for the Epsilon-180ED. This precision 7-element, 5-group optical design increases focal length by 1.5x while maintaining the exceptional image quality Epsilon owners expect. Engineered to correct coma across the field, it delivers pinpoint stars that remain equal to—or even better than—performance at the telescope’s native focal length. With an RMS spot size of 2 microns or less at the center and 8 microns or less across a full-frame 44mm image circle, this extender is built for serious astrophotographers who demand sharp, flat, high-contrast results at longer focal lengths.
