If you are looking for very good quality glasses, TPL ED six-element glasses made of optical glass with low dispersion will fully satisfy you.
ED glasses are dedicated especially to the observations of planets and the Moon, because thanks to the optical construction of these glasses the image remains contrasting, without visible color blur, even when using large magnifications. It is associated with a very good correction of chromatic aberration in ED glasses - the eyepiece practically does not introduce its own aberration.
FMC optics, i.e. fully coated with anti-reflective layers, to obtain the largest possible transmission coefficient of light. Easily removed exit pupil. The diameter of the eyepiece: 1.25 inches, i.e. 31.7 mm.
