  • Versatile imaging with UFC filter bases and extensions

  • Stable S70 dovetail ensures reliable telescope attachment
  • Minimal 1mm (0.04") optical path preserves focal plane
  • Accepts stepper rings for wide DSLR compatibility

UFC Telescope Adapter with S70 Dovetail

The Baader Planetarium UFC Telescope Adapter connects a telescope with an SP54 male thread to a camera using an S70 dovetail. It adds only 1mm to the optical tube length, preserving the focal plane for astrophotography. The adapter integrates with UFC filter bases and extensions for versatile imaging setups.

Upgrade from fixed camera mounts

This adapter replaces rigid, single-purpose camera attachments that limit filter options. The S70 dovetail allows quick integration with UFC filter changers and stepper rings for various DSLR bodies. The jump is worthwhile when you need modular filter management without increasing back focus.

Limits of the SP54 and S70 interface

The SP54 male thread requires a matching female thread on the telescope side for a secure connection. The S70 dovetail only mates with compatible UFC components, so it cannot attach directly to standard T-thread or bayonet mounts. The 1mm thickness is fixed and cannot be adjusted for specific back-focus requirements.

Questions about this item

Will the SP54 male thread on this adapter fit directly onto my telescope's SP54 female thread?

Yes, the SP54 male thread is designed to connect securely to a matching SP54 female thread on the telescope side, providing a precise alignment that minimises tilt.

How do I attach the S70 dovetail to my UFC filter base, and what is the common mistake?

Slide the S70 dovetail into the UFC filter base or extension until it locks; the step users miss is tightening the locking screw on the base to prevent the adapter from rotating under the camera's weight.

Does the 1mm optical tube length mean I need to refocus or adjust back-focus for my camera?

The adapter adds only 1mm (0.04") to the optical path, so it preserves the existing focal plane and typically requires no back-focus change for most DSLR or astro-camera setups.
