It features a smooth, dual-speed, 2-inch Crayford-style focuser with a 1.25-inch adapter, allowing for easy focusing and precise adjustments. The focuser has a large focusing range, making it suitable for various types of eyepieces and accessories.

The telescope comes with a sturdy, adjustable aluminum mount with an equatorial tracking system. The mount's counterweight system aids in balancing the telescope and maintaining its stability during long observing sessions. The adjustable azimuth and altitude settings allow for accurate alignment and tracking of celestial objects.

The UN0005401 telescope also includes a 25mm Pl ssl eyepiece and a 9x50 finder scope, allowing for easy object location and observation. Its compact design, despite its large aperture, makes it portable and suitable for both terrestrial and astronomical applications.

In summary, the Yiwu Yaozhou Optical UN0005401 telescope offers a large 90mm aperture, high-quality multi-coated objective lens, robust aluminum tube, dual-speed Crayford-style focuser, and a sturdy adjustable mount, making it an excellent choice for serious astronomers seeking high-quality, high-performance observation capabilities.
