Large SCT & EdgeHD Adapter V2 for Off-Axis Guider

This custom-designed adapter works in conjunction with the Celestron Off-Axis Guider (OAG) to yield a significantly larger illumination area when imaging through 9.25", 11", or 14" Schmidt-Cassegrain (SCT) and EdgeHD optical tubes. The upgraded V2 version features an extended 38 mm optical length, designed to accommodate DSLR back-focus spacing requirements when used with an OAG, eliminating the need for extra spacers or adapters. Featuring a generous 63 mm clear aperture, it allows full-frame cameras like the Canon 5D or 6D to utilize the full image circle produced by larger optical tubes for maximum edge-to-edge illumination.

【Key Features & Technical Highlights】

• Extended 38 mm Optical Length (V2 Upgrade): Specially extended to provide ideal DSLR back-focus spacing in conjunction with the Off-Axis Guider without extra adapters.

• 63 mm Clear Aperture: Maximizes the full image circle of 9.25", 11", and 14" optical tubes, significantly reducing vignetting on full-frame sensors.

• Black Anodized Aluminum Construction: Precision machined from high-grade aluminum with an anodized black finish; internal surfaces are sandblasted to reduce reflections and maintain high contrast.

• Knurled Grip Surface: Exterior knurling provides an easy gripping area for effortlessly threading and unthreading the adapter from the telescope.
