1.5\u00d7 Extender for the Epsilon-160ED<\/h3>\n

The Takahashi extender for the Epsilon-160ED increases the focal length to 800 mm, at an F\/D ratio of 5, for photographing objects with a tighter frame. Its seven-element, five-group design is tailored for this hyperbolic Newtonian astrograph and covers a 44-mm image circle.<\/p>\n

Compatibility and Installation<\/h3>\n

The extender is designed for the Epsilon-160ED and replaces the original corrector at the rear of the eyepiece holder. It is not compatible with the older Epsilon-160. Its input has an M60 \u00d7 0.75 male thread, and its output has an M54 \u00d7 0.75 female thread. The specified backfocus is 56.2 mm. A wide-field T-ring adapted to the camera body or camera mounts completes the setup described in the Takahashi diagram. For filters, use a clip-on filter in the housing or a filter wheel with a camera: the distributor advises against using the M48 mount in the extender due to reflections, and the standard screw-in mount in the T-ring is no longer available with this setup.<\/p>\n
