The KSON KTE900135EQ4 reflector Telescope is mounted on a German Equatorial mount. The mount features very solid metal construction, setting circles and locking knobs in declination and right ascension, counter balance shaft and weights, latitude adjuster, and slow motion controls with detachable flex cables in both axis, enabling precision micro vertical and horizontal manual tracking. A motor drive can also be attached for added tracking capability (motor drive sold separately). The Mount is attached to a very sturdy, fully adjustable, pre-assembled metal tripod with retractable rubber feet. The telescope attaches to the EQ mount by an adjustable tube clamp which in combination with the adjustable counter balance weights ensures easy fluid movement of the telescope at all times. 


The KSON  KTE900135EQ3 optical tube assembly features a 900mm focal length. The objective lens is a hand-crafted parabolic 135mm mirror with higher reflectivity coating, surface is protected by SiO2 coating. The tube itself is Zinc-plated steel, painted flat black internally for excellent visual and CCD imaging. It has a resolving power of 0.86 arc seconds. The optical tube assembly is diffraction limited at λ4 (1/4 wave in Sodium light). The tripod also features an accessory tray with slots to place 4 1.25” eyepieces or lenses. The telescope is equipped with a KSON red dot finder - with the help of convenient which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects. It includes two eyepieces: 1.25” Kellner 25mm and Kellner 10mm and a 3x 2-element Achromatic Barlow.

Start observation with Kellner 25mm eyepiece is always better with a long focal length eyepiece - it gives you a larger and brighter field of view and is perfect for finding the celestial bodies. The second eyepiece allows you to study astronomical objects with great magnification.

The 135mm primary mirror gathers up to 372 times more light than the naked eye, and is capable of showing you many objects in the Solar System and beyond: lunar craters and maria, phases of Venus, the planetary disk of Jupiter and four of its moons, rings of Saturn, Titan, binary stars and star clusters, and even nebulae and galaxies of deep sky objects.
