Orion Optics UK Adapters

Orion Optics UK adapters connect cameras, correctors and eyepieces to Orion Optics UK telescopes at the correct back focus distance. The range includes 85mm fixed adaptor rings to M54x0.75, M42, 2" and AP 2.7" threads or 1.25" and 3" push fit, Atlas ZTA adapters, and AG Wynne adapters for M42x0.75, M48x0.75 and QSI cameras.

Each listing gives the back focus (BFD) it uses, often with a few millimetres of adjustment, so you can match your camera and filter wheel spacing.
