The Skywatcher Quattro-8S is controlled and adjusted by us before delivery. The eyepiece output is stopped.
All Newton telescopes should be adjusted before the first use and then regularly to get a sharp image. We therefore adjust all our Newton before they leave our house.
How we adjust: About us
A telescope with 200mm aperture at 800mm focal length optimized for astrophotography.
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 need 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.
The aperture ratio allows short exposure times for deep sky objects. The so-called "seeing" - so the visibility conditions - beat at 8 inches not so dramatic to book. In our visibility conditions so acceptable and good photos and also observation results are possible or given.
For school astronomy, this device is recommended by an Astrophoto AG. (If it is better to be an "all-rounder", please take a look at the longer-firing telescopes.)
A further advantage of this telescope is the 2 "linear power pullout. This pullout separates the bearing from the adjustment, compared to the Crayford pullout, which means that even heavier loads can be withstood by four precision ball bearings Stainless steel rod is the weight of a full-format SLR is no problem!
2 "eyepieces give a beautiful impression of the celestial objects - especially with a large field of vision, nebulae and galaxies appear in a wide environment, which is particularly appealing because the objects in the room" float. "If you have less field of view, you can also see the details of the celestial objects The three-dimensional effect is less important than the larger field of view, and in the case of planets this is also relevant to Jupiter because the constellation of Jupiter's moons in relation to the planet is more beautiful to a change of the constellation after some observation time.
Details on Jupiter itself (cloud bands, large red spot) are in a 1 1/4 "eyepiece but then again equivalent in the impression - or recommended for short-focal eyepieces also here the spatial environment is no longer relevant.
