Tele Vue digital camera adapters allow solid, accurate attachment of digital cameras to appropriate Tele Vue eyepieces for "afocal" imaging.

"Afocal" means collimated light between the telescope eyepiece and camera lens. To minimize vignetting and maximize image quality, Tele Vue suggest using the following Tele Vue eyepieces, as their long eye relief best matches the internal pupil of the camera lens;

Naglers	22mm, 17mm, and 12mm Type 4 and 31mm Nagler type 5
Panoptics	35mm and 27mm
Plossls	40mm and 32mm
Radians	All - with special Radian adaptor
NB Tele Vue 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.
