NCLT - The Telescope
to darker Skies
Telescope' is a portable telescope design for Newtonian
optics to access remote seeing sites with big optical apertures,
equipment weight and size to carry. Mountainbiking
or hiking with the
lightest NCLT 12" versions
is possible to bring remote & high observing sites in reach. NCLT is based on new structural
design principles by using composite materials, high quality attachment
fasteners from anodised alloys, hazed titanium,
stainless steel, and
certain heavy duty industrial
Arm versus Truss Tube
was normally not a
discussion with portable telescopes since the advantages achieved with classic truss
tube constructions appeared obvious. However, workmaterials for
have changed, will change further, and so will
Dimensions, Light Weight, and High Luminosity
The NCLT telescope design offers significant advantages:
- Very low weight
- Low static
- Low intertia of the
OTA (helpful when observing fast moving objects)
- Ultra compact overall
- Great stiffness
- High precision and
stability - providing best tracking and observing experience
- Nearly zero
- No sensitivity against
liquid water in every climatic condition.
Both, Single Arm OTA
and Truss OTA
solutions are possible with the NCLT design. Single
Arm version allows very quick set up extending the 'real'
Truss Tube Versions are meant for
photographic applications & for bigger apertures beyond 16". It is possible to
install dovetail adapter plates to attach the OTA to an equatorial
mount. Also an optional
Nylon fabric lightshroud can be customized for covering the truss tube.
The NCLT design performs best with
fast optical ratios around F/3
A supportive truss structure is included with all NCLT Single
Arm versions. This anti-vibration solution
consists of two thin carbon fiber rods to attach to the pole
and to the tube base and Alt wheel. It is stopping vibrations instantly. You
don't need them when you observe with lower or mid magnification. However, it will reduce vibrations at high magnifications.
The obstruction (shading) caused
from the Valien struts is
Focuser and Coma Corrector
Feathertouch Focuser from Starlightinstruments
are meeting the requirements for visual and 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 prefer a
special lightweight focuser in combination with the
SIPS from Starlight
For 12" F/3.5
instruments we recommend the lighter Baader
MPCC in a HC-2 focuser.
Baffle, Dew Shield, Dew Heaters, and more Accessories can be installed
attached as Upgrades
Protection against Wind and Light
Lightweight beach shelter tents
are ideal to use with
MOUNTAIN telescopes. Set up in minutes,
against straylight and wind while weighing only a couple of
pounds. They are enhancing the contrast for deep
sky observing with the low standing
12" MOUNTAIN instrument.
Sitting on a mat leads to great convenience (vs.
balancing on a
ladder in the darkness). Sitting
is better than standing if you want max. visual
comfort, and concentration for getting the best possible
impressions of DS objects. A smart way of 'dome' observing
with two shelter tents...
visual observing experience may improve if you can lean back and
relax your body.
recommend a flat folding seat that supports your back like a deck
NCLT can serve as a high performance
digiscoping instrument for wildlife and
birding to catch hidden scenes of nature.
A mirror telescope
of 12" will generate brighter high resolution
is not much difference to tell to a normal fast ratio 12”
telescope and you will get the same performance depending on mirror
quality, observing skills, performance of the eye, and the
diffraction image caused from the two blade secondary cage is not
striking - just a faint unidirectional spike pattern, unlike most
radial spike patterns caused from common 4 or 3 arm spider mounted
center of gravity in NCLT instruments is very low so that
collimation-stable and vibration-free observing.
It will require a low observing position, e.g. to sit on a
or on a mat on the ground depending from the angle of altitude and the
size of the optics and ratio. Of
course, it is possible to put the scope on a higher level. Children like NCLT MOUNTAIN telescopes due to their low
observation is possible without ballast
weight. However, the included water
ballast system, or a plastic-encased dumbbell weight disc (from a gym shop) 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 any ballast.
5lbs ballast weight is enough for balancing 12" MOUNTAIN telescopes
heavy eyepieces plus coma corrector or even a camera. 16inch and bigger NCLT
telescopes will not need ballast for most observing
offer (donut shaped) water ballast bags for the 12" MOUNTAIN
size. The eyepiece weight may be limited in rather
low positions but we,
at such low positions with rather
eyepieces or web cams allow viewing on screen. The included bungee
counter system allows change of eyepieces without the instrument
loosing its position.
