| This 127mm (5") aperture Newtonian reflector optical tube has all-glass mirrors. Each mirror is coated with highly reflective aluminum and overcoated with quartz for long life. No plastic mirrors. The aluminum optical tube has protective tube end rings and a dust cover. The 1000mm focal length f/7.9 focal ratio optics can provide both low power wide angle views and high power close-ups. An achromatic relay lens in the focuser drawtube keeps the tube length conveniently short, despite the 39" focal length of the system.
The reflector design of the scope is totally free of the purple haze of spurious color visible around the Moon and planets in lesser refractor scopes. Images are sharp and clear. You can collimate both the primary and diagonal mirrors for the sharpest images. This will have to be done only rarely, thanks to the special design of the cell holding the lightweight primary mirror.
The 2" rack and pinion focuser has a 1.25" eyepiece adapter so you use it with the widest possible variety of eyepieces. The focuser has dual focusing knobs for precise image control with either hand. The large focus knobs are easy to operate, even while wearing gloves or mittens in cold weather. There is a base for a finder (not supplied) and a removable clamshell mounting ring designed to fit Meade DS mount fork arms only.
