TA-TKA68595 - Takahashi Epsilon Extender 1.5X E-180ED
TA-TKA68595 - Takahashi Epsilon Extender 1.5X E-180ED
About This Product
Takahashi has released a series of 1.5X extenders for the Epsilon series of telescopes. The extenders provide a 1.5 times increase in focal length and are comprised of 7 optical elements in 5 groups. This design provides ultra-high performance that corrects coma aberration on each the model of Epsilon telescopes. Even at the extended focal length, the star image is equal to or better than that obtained at the native focal length of the telescope. In all models, the extender provides an RMS spot size of 2 microns or less at the center of the field, and 8 microns or less at the diameter of a full frame sensor (44 mm).

The Epsilon series of astrographs are specifically designed for exceptional astrophotography. Takahashi’s proprietary optical design features a hyperbolic, concave primary mirror with a 2 element ED corrector lens to eliminate spherical aberration and coma. Compared to the conventional Schmidt camera design, the chromatic aberration is reduced by half, even out to large viewing angles.

The ε-180 was introduced by Takahashi as the first of the new Epsilon flat–field hyperbolic astrographs since the 1980’s. The ε-180 was designed to be a very fast f/2.8 imaging system.

This fast field photo visual astrograph is perfect for digital SLRs and CCD cameras. The f/2.8 speed will enable the imager to record faint nebulosity not visible in slower instruments. In addition, the appreciably shorter exposure times reduce tracking error and will produce pin point stars. The ε-180 will produce 10 micron stars across the entire 44 mm diameter flat 5 degree field.

The focuser has been improved to allow more precise focusing. Each has a metal insert with a special non-cold flow material to allow for correct focus.
