  • UFC Telescope-Adapter S70a to M54i – Optical height: 1.5 mm

    The Baader UFC Telescope-Adapter S70a to M54i creates a rigid, ultra-low-profile connection with just 1.5 mm of optical height, preserving critical back focus in complex imaging trains. This adapter connects the telescope-facing S70 female dovetail of the Baader UFC Base to focusers, flatteners, or reducers that terminate in an M54 female (M54x0.75) thread.

    Baader UFC System: The 1.5mm S70 to M54i Telescope-Side Adapter

    Integrating a filter changer into an optical path requires precise spacing, and this adapter is engineered to consume the absolute minimum. Its 1.5 mm optical height is essential for imagers using correctors or reducers with strict back focus tolerances. The adapter features the male S70 dovetail ("S70a") required to mate with the UFC base and a male M54 thread ("M54i") that securely screws into your telescope's M54 female port. This purpose-built component ensures a non-flexing link between your telescope and the UFC system, maintaining perfect optical alignment.

  • What is the primary use for the Baader UFC S70a to M54i adapter?

    This adapter is designed specifically to connect the telescope side of the Baader Universal Filter Changer (UFC) Base to a focuser, flattener, or other accessory that has an M54 female thread. Its main purpose is to establish this connection while adding only 1.5 mm to the optical path.

    Why is the 1.5 mm optical height of this UFC adapter important?

    Many modern optical systems, especially those with focal reducers or field flatteners, have very strict back focus requirements (typically 55 mm). The ultra-thin 1.5 mm profile of this adapter uses up a minimal amount of that precious distance, leaving more room for other essential components like off-axis guiders or rotators.

    How do I attach this UFC S70a to M54i adapter to my filter changer?

    This is a telescope-side adapter. You first screw the M54 male thread into your focuser or corrector. Then, you align the S70 male dovetail on the adapter with the S70 female dovetail on the UFC Base and secure it using the base's locking screws.

    Will this UFC adapter fit my Sky-Watcher Esprit 100ED focuser?

    Yes, many Sky-Watcher focusers, including those on the Esprit series, use an M54 female thread on their drawtube or included adapters. This UFC adapter is an excellent choice for integrating the Baader UFC system with those telescopes while maintaining a minimal profile.

    Can I use this Baader S70 to M54i adapter on the camera side of the UFC base?

    No. This adapter is specifically designed for the telescope side of the UFC Base (which has an S70 female dovetail). The camera side of the UFC Base has an S70 male dovetail and requires a corresponding camera-side adapter with a female S70 dovetail receiver.

    I have an M54 male thread on my flattener. Is this the correct UFC adapter?

    No. This adapter has an M54 male thread, designed to screw into a female port ("M54i" where 'i' stands for internal/female). If your flattener has an M54 male thread, you would need a different UFC adapter that has an M54 female thread to receive it.
