Q: 7. 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?

A: Yes that is correct. 10 or 12mm will be okay. It also depends on how large of an aperture your scope has. The bigger front opening of the scope the brighter the image.
