With a 200mm primary mirror, the Sky-Watcher Newton 200 is one of the amateur instruments capable of revealing many deep-sky objects and details on the planets and the Moon. In fact, it collects 78% more light than a 150mm telescope and promises years of observations rich in discovery for both beginners and amateur astronomers.

Its Newtonian design offers several advantages over other instrument families (Cassegrain telescopes and binoculars). Mirrors are more economical to manufacture for the same diameter, and their focal ratio is generally very low. You therefore benefit, for an attractive budget, from a bright telescope offering a wide field of view (here f/D = 5) . The central obstruction is also weaker than that of Cassegrain-type telescopes.

Unlike cheaply made or small diameter Newtonian telescopes, the Sky-Watcher 150, 200, 254, and 300 mm Newtonian telescopes have a parabolic primary mirror . The mirrors are spherically ground and then recut to a more expensive and difficult-to-achieve paraboloid shape. This is an essential selection criterion for instruments larger than 130 mm and with short f/D .

Focusing is achieved via a dual-coil Crayford eyepiece holder. It enables fine focusing thanks to the 1:10 gear ratio . This is a significant advantage during high magnification observations and imaging. It can withstand heavy loads (e.g., APN) . A 31.75 mm adapter is supplied as standard for using the same format eyepieces starting at a 50.8 mm output. A clamping screw located on the bottom of the eyepiece holder allows focus to be maintained depending on the orientation of the optical tube.

To present the least possible obstruction, the secondary (flat) mirror mounting bracket has four thin, 0.5 mm wide branches . Sufficiently rigid, they thus limit diffraction spikes in bright stars and excessive brightness loss. A 9x50 achromatic finderscope is also supplied as standard in its mount, as well as a 28 mm (55°) LET eyepiece for low-magnification (wide-field) observations. It will be complemented by a short focal length eyepiece for planetary observations at high magnifications.

Everything you need to know about the Sky-Watcher HEQ5 mount

A "lightweight" version of the imposing NEQ6 Pro mount, the HEQ5 Pro is aimed at amateurs and beginners looking for a portable, attractively priced GOTO mount . Tracking quality is improved with the Pro series compared to previous versions without autopointing. Long-exposure astrophotography sessions on the least bright objects are possible. An autoguiding port is even included as standard to significantly improve the periodic error in right ascension.

The HEQ5 Pro is a very attractive solution for supporting many telescopes up to 235 mm in diameter. It allows the beginner to begin imaging using a PC and a second parallel instrument when autoguiding is activated. Visual observers will appreciate the SynScan Go-To automatic pointing system provided via an easy-to-use hand controller . In fact, it is not necessary to know the position of stars or distant deep-sky objects; the HEQ5 Pro takes care of moving the instrument to the target you wish to observe.

Go-To Automated Time Clock System

After calibration (parking) with the polar finder on North Star, select mount alignment on one, two, or three stars. The database contains over 49,200 objects, including all major catalogs (Messier, NGC, IC, as well as the planets, the Moon, and the Sun). For maximum convenience, the mount moves quickly, up to 3.4°/sec, via the control panel. Easy to use, it helps you quickly point the instrument at any galaxy, nebula, cluster, or object in the solar system. Discover in detail the famous Andromeda Galaxy, the fabulous dresses surrounding the heart of Orion, the Hercules cluster M13 and its heart rich with thousands of stars. Saturn, Jupiter, and the Moon are also wonders to be explored without restraint.

The date, time, and observing location indication on the mount, combined with the "Tour" function, allows you to point the HEQ5 Pro mount at the most interesting objects throughout the evening . Take a guided tour of the sky at your observing location by clicking the "Enter" button based on the object presented in a drop-down list. Pointing accuracy can be up to 1 arc minute by compensating for mechanical errors in the mount . This procedure, called "Backlash," requires measuring the time between two opposite mount movements. The operation is simple and saves precious time, especially in astrophotography. The object you want to photograph is usually in the center of the sensor... a real pleasure!
