With aperture of 4.7", the Sky Watcher refractor from Orion is equipped with a multi-coated 120mm achromatic lens and 1000mm focal length (f/8.3) and has provided me with sharp, high-contrast images of lunar, planetary nebula and galaxies subjects.
The sturdy equatorial mount provides a stable platform for the OTA and features enclosed worm gears, dual slow-motion controls, dual setting circles, and an adjustable-height aluminum tripod with accessory tray.
I have had scope for 2 years, have kept it in pristine condition and have used it probably less than 20 times, always at home and always stored indoors. Optics perfect, no dents, very little signs of use. Dual Axis Motor Drive and original accessories included.
