TAKAHASHI FCT-L CO RING 100DF

The Takahashi TKA19200 FCT-L CO Ring 100DF has M72 x 1 female threads on each sides and allows you to connect the FCT-L 0.99x Flattener or 0.8x Reducer to common image trains using additional adapters. This particular ring has the correct spacing for FC-100DF telescopes.

With an optical thickness of 23mm, the FCT CO Ring 100DF provides the right spacing for optimal correction with each optical system.

In order to connect the FCT-L to your image train, you will need to purchase the additional TKP00200 M72 x 1 - M48 x 0.75 adapter or TKA00201 M72 x 1 - M54 x 0.75 adapter (both sold separately). These can then be connected to the CO Ring to give a backfocus requirement of 55mm for the image train.
