Sky-Watcher Teleskoop N 200/1000 Explorer 200P EQ5

There are few telescopes that can be said to be universal – the BKP 200/1000 EQ5 definitely belongs to this group. The main element of this telescope is a large parabolic mirror with a diameter of 200 mm (8 inches) and a focal length of 1000 mm. In the new version we find a precise Crayford extractor with a diameter of 2 “with a reduction to 1.25” enabling the use of virtually all available glasses on the market. This type of extractor is an innovative design that allows for much more precise focusing and works more smoothly than standard rack extractors. In addition, the extractor has a T-2 thread, to which, thanks to additional reductions, we can mount a “SLR” type camera. Sky-Watcher is a leading brand on the astronomical equipment market.

Optical system
It is a Newtonian reflecting telescope. Due to its high brightness, it is especially recommended for observing deep sky objects such as star clusters, galaxies or nebular objects. At the same time, this model allows the use of high magnifications, making it also perfect for observing planets and the moon.

The main advantage of this telescope is a large parabolic mirror with an aperture of 203 mm and a focal length of 1000 mm. A telescope with these parameters still allows for a fairly wide field of view. A mirror of this size collects about 320 times more light than the human eye at night, providing the ability to observe objects up to 13 magnitudes (up to 6 magnitudes with the naked eye). The size of the mirror is also related to the optical resolution, which in this telescope allows it to separate stars that are more than 0.7 ”apart.

In addition, the telescope includes a Barlow lens, which, in combination with an eyepiece with a diameter of 1.25 “, will give us a double increase in magnification. The equipment of the telescope should be supplemented with additional eyepieces: one with a short focal length of approx. 4-5 mm for planetary observation and one two-inch wide-angle, approx. 25-30 mm, enabling the survey of the sky or observation of vast nebular objects.

Installation
The telescope is mounted on a strong EQ-5 equatorial mount. A mount of this class offers exceptional stability and precision along with many other useful functions that are useful to anyone, even an advanced astronomer. The mounting head rests securely on the wide mounting platform of the stainless steel tripod and is equipped with a useful table for accessories. The set also includes a level indicator (spirit level), adjustment of the latitude setting with a micrometric scale and an azimuthal adjustment of the polar finder scope to the polar star. The EQ-5 also features engraved aluminum setting rings and micromovement knobs.

The assembly has the option of mounting a polar scope. We can also equip it with a drive in one or two axes or convert it into an automated assembly with the Go-To system, thanks to which we will be able to automatically target and track objects.

Extract
The telescope is equipped with a precise Crayford eyepiece extractor that allows the use of 2 “and 1.25” eyepieces. Compared to standard rack lifts, found in similar telescopes from other manufacturers, Crayford lifts offer greater precision and smooth operation. The set includes two 1.25 ”glasses.

Astrophotography
The BKP 200/1000 EQ5 telescope is a telescope that can be successfully used in astrophotography, thanks to the solid mounting of the EQ5, which has great expansion possibilities. Thanks to the large aperture and f / 5 aperture, it is possible to obtain interesting effects even with a relatively short exposure time. An additional advantage of this telescope is the two-inch eyepiece extractor.
