Sky-Watcher Teleskoop 120/1000 EvoStar EQ3-2

A large achromatic refractor designed for more demanding lovers of the night sky. The lens diameter of this optical instrument is 120mm and the focal length is 1000mm. A telescope with such parameters will be very good for observing the Moon and planets. Thanks to the large aperture for a refractor, this telescope also offers great opportunities for observing deep sky objects, such as star clusters, galaxies or nebulae – to observe these objects, it is worth equipping the telescope with an eyepiece with a focal length of 35-40mm.

Optical system

The BK 1201 EQ3-2 telescope is a typical refractor designed as a classic achromatic doublet. With a focal length of 1000mm and a diameter of 120mm, this telescope has a moderate light intensity of f / 8.3. The objective lenses are covered with anti-reflective coatings to improve the contrast and brightness of the image. The set includes 10mm and 25mm Kellner glasses and a 2 “angular adapter with a 1.25” reduction.

Installation

The telescope tube is mounted on a stable EQ3-2 equatorial mount. It is a relatively massive structure, sufficient for photographing the sky with telescopes up to 150mm in diameter, but at the same time light enough that such equipment can be considered quite mobile. The assembly is equipped with precise micromovements, what’s more, it is possible to connect quite advanced drives such as SynScan GoTo (the so-called Upgrade Kit EQ3-2). The EQ3-2 mount allows for the attachment of telescopes equipped with a Dovetail mounting rail in the Vixen standard

Spectacle lift

The BK 1201 is equipped with a 2 “Rack & Pinion eyepiece extractor. The extractor is terminated with a retaining ring with screws clamping 2-inch accessories. There is a standard Sky-Watcher finder attachment on the extractor body. Sky-Watcher.

Astronomical observations

The Solar System:

Small features on the lunar surface – but no smaller than 1.5 km, caps on Mars, even more details in Jupiter belts, numerous comets, brighter asteroids

Stars:

Approximately 1.85 million stars across the sky, up to about 12-12.5 magnitude, double and multiple stars separated from each other angularly more than 1 “.

Nebulae objects

Hundreds of star clusters, nebulae and galaxies (many of them have a visible spiral structure), many objects from the NGC and IC catalogs. Considerable detail in nebulae and star clusters. Spiral arms in galaxies invisible.
