A gear reducer designed specifically for the FS-60<\/h3>\n

The Takahashi RD C0.72X, part number TKA20580B, is an optical accessory designed for the FS-60CB and FS-60Q telescopes, as well as the older FS-60B and FS-60CSV models. It allows you to set up a photographic mount using this family of telescopes. For each version, the Takahashi assembly diagram remains the standard for selecting adapters and configuring the optical train.<\/p>\n

Connect the housing or the camera<\/h3>\n

The mechanical input uses an M56x0.75 female thread, and the output uses an M52x0.75 male thread. A camera body is connected using a wide-angle T-ring specific to the FS-60 and the camera brand. This ring is a mounting component that must be provided separately; it is not an accessory listed as included with the adapter.<\/p>\n

Follow the editing cut<\/h3>\n

The specified mechanical backfocus is 56.2 mm. This distance must be taken into account when assembling a CMOS or CCD camera, with or without a filter wheel. The manufacturer specifies a corrected image circle of 40 mm; this value describes the corrected field of view of the accessory and does not guarantee uniform coverage for all sensor and mount configurations.<\/p>\n

A compact accessory designed to be integrated into the optical train<\/h3>\n

The published length is 48 mm, with a weight of 180 g. Before installation, check your telescope\u2019s mounting interfaces and the available distance to the sensor. The specifications below apply only to this part number: they do not describe a kit that includes a scope, a camera, or a filter wheel.<\/p>\n
