The Orion AstroView 120ST EQ Refractor Telescope is a compact, rich-field refractor designed for observation of nebular clouds, star clusters and even galaxies. It has the same 120mm (4.7") clear aperture as the standard AstroView 120, but the 120ST's multi-coated achromatic objective lens has a focal length of just 600mm (f/5) compared to 1000mm (f/8.3) for the standard model.
That translates to a 66% wider field of view for any given eyepiece. With the included 25mm Plossl, the 120ST covers a sprawling 2.1° swath of sky - enough to display the entire Double Cluster, Pleiades Cluster, or North America Nebula! The fast f/5 optical system also makes it an excellent telescope for astrophotography. The cast-metal 2" rack-and-pinion focuser accommodates either a 1.25" or 2" diagonal, so you can use optional 2" eyepieces for an even dreamier wide-field effect. The 6x30 finder scope features an aluminum dovetail bracket with easy, two-screw adjustment. The two 1.25" Sirius Plossl eyepieces provide good, sharp views at 24x (25mm focal length) and 60x (10mm focal length).
A 1.25" mirror star diagonal is also included. The optical tube measures just 26" long including dew shield, so it earns high marks for portability. It comes with the AstroView equatorial mount, which provides the stability and smoothness of motion you need for enjoyable wanderings through the heavens. A free polar-axis scope gets you polar-aligned quickly and accurately and manual slow-motion controls let you center objects and track them effortlessly. Add an optional EQ-3M electronic drive for automatic tracking. The aluminum tripod adjusts in height and includes a roomy accessory tray.
