A 130-mm ED triplet for visual observation and photography<\/h3>\n

The Takahashi TOA-130NS combines a 130-mm objective with a native focal length of 1,000 mm, resulting in an F\/D ratio of 7.7. Its wide-air-gap triplet includes two S-FPL53 ED glass lenses. This optical design corrects chromatic aberrations to preserve sharpness and contrast in both astronomical observation and photography.<\/p>\n

Development and Assembly<\/h3>\n

The 2.7-inch rack provides focusing. The TKA31430 counterbalance collar included with the tube helps counterbalance the weight of the lens. The native back focus is 222.5 mm. The retractable dew shield reduces the space required for storage.<\/p>\n

Setting Up the Tube for Photography<\/h3>\n

The TOA-35FL corrector and the TOA-35RD reducer are available as options. To assemble the photographic train, follow the diagram for the TOA-130NS version and the selected accessory: it specifies the adapters and distances to the sensor.<\/p>\n

Contents Included<\/h3>\n

TOA-130NS tube with TKA31430 balancing clamp. The probe, its mount, and the mounting clamp must be ordered separately; the balancing clamp serves a distinct purpose.<\/p>\n

Choose a frame and mount that are compatible with the assembled unit, then check the balance and tightness.<\/p>\n
