UFC 15mm Extension S70 Dovetail with Clamp

The Baader UFC S70/15 Extension provides a fixed 15mm spacing option within the Baader Universal Filter Changer (UFC) system, featuring an S70 dovetail clamp on the telescope side and S70 dovetail receptor on the camera side. This precision-machined extension allows astrophotographers to fine-tune the optical back focus distance between their telescope and camera or filter base, and can be stacked with other UFC extensions to achieve the exact spacing required for optimal imaging. The extension integrates seamlessly into the UFC modular system and is compatible with the UFC filter base and various telescope-side adapters featuring S70 dovetail connections.
