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 and less
equipment weight and size to carry.
or hiking with the
lightest NCLT 12" versions
is possible and allows to access very dark and 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 versions contain a very small number of parts for a mirror telescope. Set up is very quick!
Travel telescopes work great at short focal lengths showing compact dimensions and high luminosity
Carbon composite materials built in smart telescope constructions 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 possible, NCLT with Single Arm or NCLT with Truss Tube. Set up of the Single
Arm version is quick and will provide longer 'real' observing time and more convenience at a wide range of
magnifications. NCLT works best at optical ratios around F/3
- F/4 - ideal ratios for versatile and simple set up/take down travel telescopes.
NCLT telescopes come with Single Arm tube or optionally with a sixXalien Truss Tube to
use it also for photographic applications. It is possible to
install an attached connection plate for equatorial mounts. That will lead to an extreme
lightweight, though, powerful astrophotography instrument with the
additional option of air travel.
triangular NCLT geometry combines highest stiffness and lowest weight,
and the least possible complexity of a Newtonian Mirror Telescope.
Valien stops vibration
An alternative 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, enhancing a bit the
static integrity and stopping vibrations instantly.

We also offer strings (coated steel cable - 0.3mm thick) to use for extra vibration damping. For
observing it is actually not neccessary to use the

focuser. It is ideal with
LiteScope NCLT Travel Instruments for ratios around F/3. We use a certain
lightweight focuser in combination with the SIPS.
An optional upgrade:
focusing with an I-phone and a 'Focuser Boss II'
For 12" F/4-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.

They weigh only a couple of pounds and enhance contrast for deep sky observing

Sitting deep leads to better convenience vs.
balancing on a
ladder in the darkness. Sitting
is better than
standing when you want
to observe with maximum visual sensitivity,
comfort, and concentration to get better
impressions of DS objects. This is a smart way of 'dome' observing.
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 tool for wildlife and
birding. It will help to catch most hidden scenes of nature.
A mirror telescope

struts offer enough stiffness to allow even bino viewers. It will
have to be
balanced by using additional counter weight.
Also the set up & take down and packing time may need a few minutes longer.
For most visual observing we recommend the single pole instruments, but the truss
tube upgrade 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 bungee cord system cares for the fine adjustment. Here, it is showing with F/4 optics in the MOUNTAIN classic 12" instrument.
Observing is generally possible without any ballast weight, though the sand or water
ballast system or a plastic dumbbell weight disc will relieve the bungee

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 which can be filled individually. The eyepiece weight may be limited in very low positions but you
mainly planets at such lower positions with rather small
eyepieces or web cams can be also a great way to view on screen or to stack images.
The included bungee
counter system makes your eyepiece change easy, without the scope
loosing its position.
