Everything you need to know about the Newton Sky-Watcher 200mm f/5

With a 200 mm primary mirror, the Sky-Watcher Newton 200 is one of the amateur instruments capable of revealing numerous deep sky objects and details about the planets and the Moon. In fact, Captures 78% more light than a 150mm telescope and promises years of discovery-filled observations for beginners and amateur astronomers alike.

Its Newton design offers several advantages over other families of instruments (Cassegrain glasses and telescopes). Mirrors are cheaper to manufacture for the same diameter and their focal ratio is generally very low. Then you can benefit, for an attractive price, from a bright telescope that offers a large field of observation (here f/D=5) . The central obstruction is also weaker than that of Cassegrain-type telescopes.

Unlike very cheaply made Newton telescopes or small diameter, the Newton Sky-Watchers of 150, 200, 250 and 300 mm They have a parabolic primary mirror . The mirrors are polished spherically and then trimmed to achieve a parabolic shape (more expensive and difficult to obtain). This is an essential selection criterion for instruments larger than 130 mm and with short f/D .

Focusing is achieved using a dual-flow Crayford eyepiece. Allows you to obtain fine focus thanks to 1:10 reduction . A very noticeable advantage during observations with high magnifications and when taking images. Can support heavy loads (e.g. APN) . A 31.75mm adapter is supplied as standard to use eyepieces of the same format from the 50.8mm output. An adjustment screw located at the bottom of the eyepiece holder allows you to maintain focus by following the orientation of the optical tube.

To present the least possible obstruction, Secondary (flat) mirror mounting bracket has 4 thin branches , with a width of 0.5 mm. Being sufficiently rigid, they limit diffraction peaks in bright stars and excessive luminosity loss. Also supplied as standard is a 9x50 achromatic finderscope on its mount, as well as a 28mm (55°) LET eyepiece for low-magnification (widefield) observations. It should be completed with a short focal length eyepiece for planetary observations at high magnifications.

Everything you need to know about the Sky-Watcher NEQ5 mount

The Sky-Watcher NEQ5 Equatorial Mount It is a versatile mount, worthy heir to the legendary Vixen GP . Very modular, it is possible to add several options depending on whether it is intended for observation or photography: motorization, Goto automatic aiming kit, polar scope, etc. Its load capacity is close to 9kg in visual observation. ; The NEQ5 will therefore support numerous optical tubes, from the small 80mm refractor to the Newton telescope up to 200mm in diameter.

In photography we will limit the load to 7.5kg, for greater comfort and precision. Like all equatorial mounts, the NEQ5 is equipped with a set of azimuth and latitude movements (for parking), and a set of right ascension and declination movements for pointing and tracking the stars.

The adaptation of the optical tube is carried out using a Vixen-type female dovetail. An accessory tray guarantees good rigidity of the set. The NEQ5 mount can accommodate a polar finder (option #SW0124 ) on the polar axis for quick station setup. The visual observer will appreciate the GOTO SynScan automatic signaling system (optional) delivered via an easy-to-use hand controller. In fact, it is not necessary to know the position of stars or distant bodies in the deep sky, the Go-To system of the NEQ5 mount is responsible for moving the instrument towards the target you want to observe.
