The SIGETA StarQuest 135/900 Alt-AZ incorporates a unique design and high-quality optics. With this model you can view not only the planets of the solar system, but also distant nebulae, galaxies and star clusters.

The main mirror has a special anti-darkening coating. A middle-mounted marking simplifies adjustment. The kit includes: 25mm Kelner eyepieces, 10mm Pleslas and a 3x achromatic Barlow lens. The eyepieces are fully multi-coated allowing contrast and sharp images. The achromatic Barlow lens not only magnifies the image by three times, but also offsets both spherical and chromatic aberration. The Red dot eyefinder has an optical lens with zero magnification and aims at bringing the target precisely to the desired object.

The alt-azimuth mounting is easy to install and operate. The optical tube can be turned horizontally and vertically. It can be controlled with special knobs on the mount. The tripod is made from lightweight and stable steel. A level on the tripod will ensure correct, even positioning. The height is adjustable and its legs are covered with rubberised material. The set also includes an equipment tray for accessories, providing sturdiness to the tripod.

The Newton Reflector SIGETA StarQuest 135/900 is an ideal aid for space exploration. Its characteristics and equipment let you enjoy celestial objects to the full.
