NCLT - a Telescope 'to go' to darker Skies
Observing
'New Cambridge Lightweight 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.

Mountainbiking 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 fasteners from
stainless steel, anodised alloys, hazed titanium and certain heavy duty
industrial plastics.


Single Arm versus Truss Tube was normally not a big discussion with portable scopes since the advantages achieved with common
truss tube constructions appeared obvious. But workmaterials for telescopes have changed however and they will change further and
so will the designs..

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.
The triangular NCLT geometry combines highest stiffness and lowest weight, and the least possible complexity of a Newtonian Mirror Telescope.

Valien  stops vibrationValien

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.
You need them not when you observe with lower or mid magnification, but it helps to reduce any
vibrations at a higher magnification, sufficiently.
The obstruction (shading) caused from the Valien 
struts is neglectable.

We also offer strings (coated steel cable - 0.3mm thick) to use for extra vibration damping. For most visual
observing it is actually not neccessary to use the vibration stopper equipment - it is recommended at certain
higher
magnifications.



           

Focuser and Coma Corrector
SIPS

Lightweight Feathertouch Focuser from Starlightinstruments are meeting the requirements for 
optional photographic purposes for advanced travel and backpack instruments in very fast F/3
telescopes.

 
SIPS is a combination of an optical ParaCorr II Coma Corrector from TeleVue with an attached 
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: wireless 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.

   Iris Baffle, Dew Shield, Dew Heaters, and more Accessories can be installed or attached as Upgrades

Wind and Light Protection
observing shelter against straylight and wind

Lightweight observing shelter tents are ideal to use with NCLT MOUNTAIN telescopes.
They are set up in minutes to protect against straylight and wind - ideal for
observing
Deep Sky objects ...
 
They weigh only a couple of pounds and enhance contrast for deep sky observing
with the low standing 12" instrument. 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 of 12" will generate brighter high resolution pictures and films of
shy or nocturnal animals.


Truss Tubes

12 inch MOUNTAIN with Truss Tube
siXalien truss tubes are an optional assembly (upgrade) to fit on an NCLT telescope
base. Six Carbon 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.
For many experienced astronomers it reflects rather familiar construction principles..
.



Upgrades like DSC or Dob Driver systems are basically possible to attach in most
NCLT telescopes.


 

Observing
 


There is not much difference to tell to any normal fast ratio 12” Dobsonian telescopes and you will get the same performance as in any such good telescope depending from the mirror quality, your observing skills and the performance of your eyes and the available atmospheric seeing. The diffraction image caused from the two blade secondary cage is not striking: just a faint unidirectional spike pattern, compared to the most common radial spike patterns caused from classic 4 or 3 arm spider mounted secondary mirrors.

 

KidsKids and MOUNTAINThe center of gravity in the NCLT instruments is very low so that the structure provides collimation-stable and vibration free observing, but without the usual heavy chunky equipment to carry around.

It will require a low observing position and to sit on a small chair or on a mat, on the ground, depending from the angle of altitude.

Of course it is also possible to put the scope on a higher level .

Children like the NCLT MOUNTAIN telescopes with its low 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 generally possible without any ballast weight, though the sand or water ballast system or a plastic dumbbell weight disc will relieve the bungee system, making more convenient to balance the scope is  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 ballast. About 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 might observe mainly planets at such lower positions with rather small eyepieces. Electronic 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.
