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 but less equipment weight and size to carry.


Mountainbiking or hiking with the lightest NCLT 12" versions is possible and will allow 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 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 and they will change further and
so will the designs.  

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 but with the options of a travel telescope.
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.

The triangular NCLT geometry combines the highest stiffness, the lowest weight, and the least possible structural complexity of a Newtonian Reflector Telescope.
Valien
Valien  stops vibration

An additional truss structure solution is included with all NCLT Single Arm versions - Valien strutsIt 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.
You don't need them when you observe with lower or mid magnification, but it will reduce vibrations at high magnifications,
sufficiently.
The obstruction (shading) caused from the Valien struts is neglectable.

 

SIPS
Focuser and Coma Corrector 

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 
lightweight 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.

observing shelter against straylight and wind
Wind and Light Protection

Lightweight observing shelter tents are ideal to use with NCLT MOUNTAIN telescopes.
Set up in minutes, they protect against straylight and wind while
weighing only a couple of pounds
enhancing contrast for deep sky observing with the low standing 12" instrument. Sitting on a mat
leads to great convenience (vs. balancing on a ladder in the darkness). Sitting is better than
standing when you want observe with maximum visual sensitivity, comfort, and concentration for
getting the best 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 instrument for wildlife and birding. It will help to catch the very hidden scenes of nature. 

A mirror telescope of 12" will generate better, brighter, and higher resolution digiscoping footage of
shy or even nocturnal animals.

12 inch MOUNTAIN with Truss Tube
Truss Tubes

The siXalien truss tube is an optional assembly to fit on an NCLT telescope base to produce
extra stiffness.
It will work as best at F/4 to be balanced by using additional counter weight.
Also the set up & take down and the packing/unpacking time may need a little longer
as the
single tube.
For most visual observing tasks 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 should be used with NCLT telescopes
bigger than 16".




 

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 on the mirror quality, observing skills, the performance of the 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, unlike the most common radial spike patterns caused from the common 4 or 3 arm spider mounted secondary optics.

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, e.g. to sit on a small chair, or on a mat on the ground, depending from the angle of altitude and from the size of the optics and ratio.

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

Children like NCLT MOUNTAIN telescopes due to the low eyepiece position. An ideal school telescope for young astronomers.

The bungee cord system cares
for fine adjustment. Here showing with F/4 optics in the MOUNTAIN classic 12" instrument. 
Observing is 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.

Normally, there is no need to change the counter weight when changing the eyepieces. Light or mid weight eyepieces do not require 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 for the 12" MOUNTAIN size. The eyepiece weight may be limited in very low positions but you may observe planets at such lower positions with, typically, rather small eyepieces. Electronic eyepieces or web cams allow viewing on screen or stacking images.

The included bungee counter system makes eyepiece change easy, without the scope loosing its position.
