Tele Vue Plossl Overview

Engineered to Al Nagler's uncompromising standards, the entry-level Tele Vue Plossl 55mm Eyepiece has the longest focal length available in their entire catalog to produce a low magnification for both near and deep-sky observations on OTAs outfitted with larger focuser drawtubes.

It is made using diffraction-limiting high-index glass lenses in a 4-element/2-group configuration to keep light on-axis and reduce astigmatism and edge-aberrations across its generous 50° apparent field of view. Fully multi-coated optics, blackened lens elements, and anti-reflection threads complement the optical components to improve contrast and light transmission, while limiting its loss. Its exceptionally-long 38mm eye relief allows users the room to back off from the eyecup for a more comfortable viewing experience with a reduced risk of accidental contact with the eyepiece lens, which can cause vibrations and interfere with views. Ideal for fast-focal ratio OTAs, the eyepiece features a 2" barrel to be compatible with larger focusers and accessories, which allows more light into the eye and creates the long eye relief; and a convenient fold-down rubber eyecup, and a rubberized textured collar to ensure a secure grip when handling it.

question

What I feel that needs to be better explained about eyepieces and focal lengths as in 6mm or 25mm is that the opening is tiny for 6 mm as compared with 25mm that is wider . The lower the focal length the difficult it gets to train your eye throughthe opening due to its tiny opening. My child experience with my first kid telescope that came with 6mm and 25mm eyepieces told me that 25mm is more enjoyable to use despite lower magnification than the higher magnifying 6mm which is so restrictive in the opening for my eye to keep peeking through as steadiily as I can. I think that a minimum of 10mm is acceptable to me or maybe 12mm. . Am I correct?

yes, you are correct. if you get a plossil eyepiece (4 element) the higher magnification eyepieces will have a smaller opening. If you go to a 6, 8 element eyepiece you will be able to go to a higher magnification with a larger opening.
