Televue Nagler 3-6 mm zoom

For experts, the name Nagler stands for top quality. And this zoom eyepiece, developed by Televue for planetary observers, is no exception: excellent contrast, image sharpness and a comfortable eye relief (10 mm) are the hallmarks of these zoom eyepieces. The field of view is 50° and parfocal over the entire focal range, meaning there is no need to adjust focus when changing magnification. The zoom eyepiece has "stop positions" at settings of 3-4-5-6 mm.
