The Skywatcher Explorer 250PDS Newton is checked and adjusted by us before delivery. The focuser is set.

All Newtonian telescopes should be adjusted before first use and then periodically for a clear image. We adjust all of our Newton before they leave our house.

Skywatcher Explorer 250PDS 1200mm 10 "inch f / 4.7 Newton telescope


10 '' telescope (Newton) with 254 (!) Mm aperture and 1200mm focal length, 2 "Crayford focuser and 1:10 micro reduction for high-precision focusing.

There are not only alternators in the car! :-)
Newton telescopes are considered (and are) basically high-powered telescopes. From f / 5 I define again as particularly bright. When observing the moon, we definitely recommend a filter to reduce the glare effect. - The moon reflects so much light that the light should be attenuated (especially at low magnification). Also note the dark adaptation of the eye. For example, if I want to observe deep sky objects after the moon, the adaptation of the eye takes a certain amount of time before I can perceive the much fainter ones again in detail.
And that brings us to the objects that such a Newton can show in abundance - visually and photographically!
Deep sky objects (ie galaxies, nebulae, star clusters ...) do not require a high magnification, but a corresponding light gathering power. For photography, this also means the shortest possible exposure time for a shot.
Planets (and moon) require a higher magnification and thus a Barlow lens ???? for focal length extension.
So with this device also beautiful details on the moon and planets can be seen! So you do not have to do without this field of application:
An (almost) all-rounder among the telescopes focusing on deep sky.

With a diameter of 25.4cm (10 "), the light gathering power is approximately 1275 times that of the eye Light faint galaxies and nebulae are considered for your observations! High magnifications and detailed images of the moon and planets are possible due to the good optics Observe structures at the moon and interesting details on planets, such as the rings of Saturn, cloud bands at Jupiter.

The 2 "Crayford focuser with 1:10 reduction:

The Newton is equipped with a smooth and precisely worked 2 "Crayford focuser with a reduction for 1.25" accessories. You can thus use powerful 2 "eyepieces, a bright picture and a broader view is possible.All 1.25" eyepieces can of course also be used.
Since the drawer is ball-bearing, heavy and accurate adjustments are guaranteed for heavy accessories.
To achieve a particularly accurate focus, the extract has a 1:10 micro reduction, for photography particularly important and proven.

Product advantages:

+ Ideal for detailed lunar, planetary and deep-sky observations
+ Through 254mm opening high light collection power (f / 4,7)
+ PDS variant with DualSpeed focuser for sensitive focusing by 1:10 reduction
