NCLT - a Telescope
to darker Skies'New
Telescope' is a portable telescope design for Newtonian optics to access remote seeing sites with
big optical apertures but less
equipment weight and size to carry.

lightest NCLT 12" versions
is possible and allows to reach very dark or high level observing sites.
NCLT is based on new structural design principles using composite materials and high quality attachment parts and
stainless steel, anodised alloys, hazed titanium and
certain heavy duty industrial plastics.
Arm versus Truss Tube
was normally not a
discussion with portable scopes since the advantages, achieved with
tube constructions, appeared obvious. But workmaterials for telescopes
have changed however and they will change further and
The NCLT design in form of the Single Arm version contains a very small number of parts, making the set up easy and quick!
Travel telescopes work great at short focal lengths showing compact dimensions and high luminosity
Carbon composite materials in smart telescope construction will lead to significant advantages:
a) reduced weight, lower static
forces and intertia (e.g. when observing moving objects)
b) increased stiffness for greater precision and stability, providing best tracking performance
c) reduced temperature drift and sensitivity against humidity or
liquid water in all climatic conditions
Both options are possible: Single Arm Tube or Truss Tube. Set up of the Single
Arm version is quick, allowing a longer 'real' observing time and more convenience at a wide range of
magnifications. NCLT telescopes with a Truss Tube are meant for photographic applications. It is also possible to
install an attached adapter plate for equatorial mounts. That will lead to an extreme
lightweight, though, powerful astrophotography instrument with the
additional option of air travel.
NCLT works best at fast optical ratios around F/3
- F/4, which is great for versatile and simple set up/take down travel telescopes.
triangular NCLT geometry combines highest stiffness, lowest weight,
and the least possible complexity of a Newtonian Reflector Telescope.
Valien stops vibration
An additional truss structure solution is included with all NCLT Single Arm versions - Valien struts. It consists of two thin Carbon
Fiber rods to
attach to the pole and to the tube base, thereby enhancing the static integrity whilst stopping vibrations instantly.
need them not when you observe with lower or mid magnification, but it helps to
reduce vibrations at high magnifications,
sufficiently. The obstruction (shading) caused from the Valien struts is
Focuser and Coma Corrector

optional photographic purposes for
advanced travel and backpack instruments in very fast F/3
is a combination of an optical ParaCorr II Coma Corrector from TeleVue with an attached
focuser. It is ideal with NCLT Travel Instruments for ratios around F/3. We use a certain lightweight
focuser in combination with the SIPS.
For 12" F/3.5 instruments we recommend the lighter Baader MPCC in HC-2 focuser.
NCLT keeps the Optics in accurate Position. Customers, Telescope Experts, and Enthusiasts have confirmed
this Fact by their own Evaluation.

Your visual observing techniques may improve when you can lean back and relax your body
while you are 'VISITING THE SKIES'.
We recommend a folding seat that supports your back like a deck chair.
NCLT can serve as a high performance digiscoping instrument for wildlife and
birding. It will help to catch the very hidden scenes of nature.

struts offer enough stiffness to allow even bino viewers. It will have
balanced by using additional counter weight.
Also the set up & take down and packing time may need a few minutes longer.
For most tasks of visual observing we recommend the single pole instruments. But the
truss tube option will, basically, allow you more weight on top of the very light NCLT
telescopes. Also an optional Nylon fabric lightshroud can be used for covering the tube.
The truss tube version is to recommend with NCLT telescopes bigger than 16".

eyepiece position. An ideal school telescope
for young astronomers.

The bungee cord system cares for the fine adjustment. Here, it is showing with F/4 optics in the MOUNTAIN classic 12" instrument.
Observing is often possible without ballast weight, though the sand or water
ballast system, or a plastic-encased dumbbell weight disc will relieve the bungee counter system, making it more convenient to balance the scope with heavy eyepieces. In
most cases there is no need to change the counter weight when changing
the eyepieces. Light or mid weight eyepieces do not require the
5lbs ballast weight is great for balancing 12" MOUNTAIN telescopes with
heavy eyepieces plus a coma corrector or even a camera. 16" and bigger telescope sizes will not need ballast for most observing tasks. We offer (donut shaped) water ballast bags for the 12" MOUNTAIN size which can be filled individually. The eyepiece weight may be limited in very low positions but you
may observe planets at such lower positions with rather small
eyepieces or web cams allow viewing on screen or to stack images.
The included bungee
counter system makes your eyepiece change easy, without the scope
loosing its position.
