Takahashi 1.5X Extender for the Epsilon 180ED

The Takahashi Extender 180ED threads onto the focuser of the Epsilon 180ED to increase the focal length by 1.5X and presents M54 threads for camera attachment. This Epsilon 180ED Extender is an optical system with 7 elements in 5 groups and does a beautiful job of extending the focal length and correcting for coma without losing any of the high performance results you enjoy at the telescope's native focal length.

The RMS spot size for the E-180ED Extender is 2 microns or less at the center of the field and 8 microns or less at the diameter of a 44 mm full frame sensor. You can take a look at the spot diagram in the images section above.
