8" Dob telescope with a focal length
of 1200mm and an aperture of 200mm. Great for amateur and experienced
stargazers alike. To make viewing the night sky as easy as possible, the
optical tube is attached to a Dobsonian mount and is very easy to
assemble - the kit includes everything you will need to assemble it. The
precision of the mount is guaranteed with manual azimuth and altitude
slow-motion controls.
To make azimuth adjustments even
smoother the azimuth slow-motion control has special roller bearings.
The telescope comes with a 2" dual-speed achromatic Crayford focuser and
a 1.25" adapter, which provide for exceptional precision during
focusing. All optical elements are made of high-quality BK-7 glass and
have a built-in cooling fan to reduce the time it takes the optics to
adapt to the outside temperatures.
This telescope comes with a 9mm
Plössl eyepiece, which yields sharp, clear views of the lunar and
planetary surfaces. Even better, the 30mm SuperView eyepiece allows you
to observe the wonders of the farthest reaches of the universe - with
it, you can study star clusters, nebulae and galaxies that lie far
beyond the Solar System.
Main features:
The primary mirror has a reflectivity index of 94%;
Built-in cooling fan;
Easy-to-use Dobsonian mount;
High-quality optics made of BK-7 glass;
Dual-speed Crayford focuser for precise focus adjustments.

This Newtonian telescope has an
aperture of 254mm and a focal length of 1255mm. This telescope is a good
choice if you are thinking about getting into stargazing. The Dobsonian
mount makes the scope easy to assemble and control. The Dobsonian mount
is very easy to assemble - the kit already includes everything you will
need to assemble it. Placed into two slots on the assembled mount the
optical tube is then locked in place with two springs. As soon as that
is done, you can begin your observations.
Made of BK-7 glass the optical
elements yields sharp high-quality views. The optical tube has a
built-in fan that cools the primary mirror and protects it from
deformation, which further adds to the quality of the produced views.
For precise focusing with no backlash
this scope comes with a dual-speed Crayford focuser. The focuser accepts
1.25" eyepieces and also has a compression ring on the focuser allows
you to attach accessories quickly. The use of roller bearings in the
azimuth slow-motion control provides for smooth and precise movements of
the mount.
An added bonus, this Dobsonian
telescope comes with a wide-FOV SuperView eyepiece (included in the kit)
to observe star clusters, galaxies and other deep-sky objects. If you
want to observe the moons and planets of our solar system switch from
the SuperView eyepiece to 9mm Plössl, and you will be able to see small
lunar craters and get clear images of Mars and even Saturn.
Main features:
Built-in cooling fan for the primary mirror;
Easy-to-use Dobsonian mount;
High-quality BK-7 glass optics;
Dual-speed Crayford focuser that ensures maximum precision during focus

This Dobsonian telescope has a focal
length of 1520mm and an aperture of 300mm. Simple to operate, the
optical tube is attached to a mount that is easy to assemble, making
this telescope a good choice for a amateur stargazer. To attach simply
slide the optical tube into two slots on the assembled mount and lock it
in place with balancing springs. Thanks to the special roller bearing,
the manual slow-motion controls are smooth and precise.
The dual-speed Crayford focuser
allows you to adjust focus with extreme precision and accepts 1.25" and
2" accessories (the 1.25" adapter included). The primary BK-7 glass
mirror has a built-in cooling fan to reduce the time it takes the optics
to adapt to the outside temperatures. Because of this feature you can
enjoy sharp, clear views with no false color.
Included with this telescope are
SuperView and Plössl eyepieces that allow you to observe the Solar
System planets as well as deep-sky star clusters, galaxies and nebulae.
