The design of the Celestron PowerSeeker2 optical tube helps reflect stray light away from the users eye, giving higher contrast planetary and lunar views. In addition, the square tube design maximizes the internal tube space allowing damaging tube currents to avoid the actual optical path - this results in clear, steady seeing. Unlike most other 60mm refractors, the powerseeker2 has a rotable erect image diagonal that makes it excellent for land viewing as well as atronomical use.
