About this product
StellaLyra 15mm Ultra Flat Field 1.25" Eyepiece
The 15mm StellaLyra Ultra Flat Field eyepiece provides a wide 65-degree FOV and excellent field curvature correction so stars are pin-sharp across the entire visible field, even in fast optical systems.
All Ultra Flat eyepieces have fully multicoated optics and blackened lens edges for high light transmission and contrast. The colour correction is excellent.
They also have generous eye-relief so are comfortable for use even when wearing spectacles and a foldable rubber eyecup provides comfort and prevents glare from stray light.
