Solid, lightweight construction: Thickened aluminum alloy body gives the adapter strong support for heavy eyepieces or cameras while keeping overall weight low for stable mounting and easy handling. Durable, lowreflectance finish: Advanced hardplating process with a sanded black surface reduces internal reflections and resists wear and corrosion for longterm, reliable use. Precision fit and fullframe clearance: CNC precision integrated manufacturing ensures tight tolerances and accurate alignment. The 2 inches fullframe opening prevents vignetting or dark corners when using widefield eyepieces or fullframe imaging sensors. Easy, reliable connection: Standard threaded interface fits directly to the telescope optical tube, providing a secure, repeatable attachment without adapters. Compatible with: C8 C925 C11 C14 C8HD C925HD C11HD C14HD. How this helps you Eliminates light falloff at the edges so you capture the full field of view with 2' eyepieces or fullframe cameras. Provides a rigid, precisely aligned mounting point that improves image quality and reduces flex when using heavier accessories. Lowreflectance finish and tight machining minimize stray light and misalignment that can degrade contrast. Typical applications 1) Fullframe astrophotography: Mount a 2' camera adapter or field flattener to capture edgetoedge illumination on fullframe sensors without dark corners. 2) Widefield visual observing: Use large 2' eyepieces on C8–C14 series telescopes for comfortable, unobstructed views across the entire field. 3) Heavyaccessory support: Securely attach cameras, offaxis guiders, or focal reducers to SCT optical tubes where a strong, accurately machined 2' interface is required.
