Tele Vue digital camera adapters allow solid, accurate attachment of digital
cameras to appropriate Tele Vue eyepieces for "afocal" imaging
(Digiscoping). "Afocal" means
collimated light between the telescope eyepiece and camera lens. To minimize
vignetting and maximize image quality, we suggest using the following Tele Vue
eyepieces, as their long eye relief best matches the internal pupil of the
camera lens; 40mm, 32mm Plössls, 35mm, 27mm Panoptics, 22mm, 17mm, and 12mm
Nagler type 4, 31mm Nagler type 5 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. Not shown in above photo, all adapters include 3
small thumb screws for easy use without tools.
