TeleVue - Afocal Adapter Ring 28mm

Details

Televue digital camera adapters allow solid, accurate attachment of digital cameras to appropriate Televue eyepieces for "afocal" imaging. "Afocal" means collimated light between the telescope eyepiece and camera lens.


To minimize vignetting and maximize image quality, we suggest using the following Televue eyepieces, as their long eye relief best matches the internal pupil of the camera lens: 40mm, 32mm Plossls, 35mm, 27mm Panoptics and all Radian focal lengths. Radian eyepieces require the adapter included with DRA-XXXX models. Overall, we found the 35mm Panoptic achieves the least vignetting in afocal applications. One more thing to note is that because camera pupils move with zooming, you may find minimum vignetting at the extremes of zoom positions. Results will vary depending on the camera used.
