Televue 14mm Radian

by Legacy Reviewer, Verified Owner from United States, MD Written on November 21, 2010
A good value for a well corrected, medium focal length eyepiece given the excellent sharpness and contrast, and of course, the very comfortable eye relief (20mm). This eyepiece sometimes gets bad press as a planetary contender. But I have found it's contrast to be on par with similar focal length Orthos I have used. I find no more blackout (or kidney beaning) problems than any other eyepiece I own. However, I have observed some lateral color (chromatic aberration) at the very last 10 percent of the field. If you use a drive when observing, you won't even know it exists.
Pros: Sharp ep; good contrast and eyerelief
Cons: Tiny bit of lateral color (at outermost edge of field)...
Would recommend: Yes
