Choose the right collar for the pipe<\/h3>\n

Part number TKA20420Q, known as the 80QS, has an inner diameter of 80 mm. Takahashi lists the following compatible models: Takahashi FS-60Q and FC-76DC telescopes. Check the model and version before installation: the diameter alone is not sufficient to determine compatibility with all interfaces.<\/p>\n

Attaching the collar to the frame<\/h3>\n

The standard one-piece collar is designed to secure the optical tube to a mount. Takahashi specifies a mounting surface with two 8.8-mm holes for attachment to its mounts using two M8 screws. Refer to the drawing for this part number to verify the center-to-center distances before choosing a different interface.<\/p>\n

A photographic mounting point<\/h3>\n

The small, flat top surface features a 1\/4-inch-20 tpi photographic-threaded screw. It allows a housing to be mounted parallel to the tube. This 80QS version should not be confused with the 80S-GT symmetrical clamp, which has a different top base.<\/p>\n

Construction and Protection<\/h3>\n

The collars are made of cast aluminum and finished by hand. The felt protects the surface of the optical tube. The listed weight for this model is 500 g. Check that your setup is securely fastened and properly balanced before use.<\/p>\n
