Hubble UL14 f/4.6 Premium Dobsonian telescope is a high-quality,
large-aperture telescope for serious observers, optimized in a very light and
compact package for extreme portability. With a Hubble UL14, you are free to
travel to your favorite dark-sky sites anywhere in the world.
Why would you select a Hubble UL14?
The UL14 is a perfect balance between a telescope with large light-gathering
capability and unbeatable portability. It will be the telescope that gets taken
out of the garage or from the back of a car to be used frequently. It will
provide stunning views of the heavens and a lifetime of observing enjoyment.
The UL14 collects 36% more light than a 12" and 96% more than 10" optics,
allowing you to resolve significantly fainter objects and more subtle details.
The UL14 has a parabolic primary with a full 14-inch diameter of optical
surface, a generous 14.4” overall diameter; not an 14-inch blank with a
beveled and much smaller optical surface like all other 14" telescopes in the
market. It translates to 5% more optical surface and light gathering
power than any other 14” scopes in the market.
Hubble UL14 has been designed to be as light and compact as possible,
making the task of transport to your favorite dark-sky site as easy as
possible. The heaviest component of the UL14 is the primary mirror, which
weighs in at about 16 pounds, and the entire telescope is only about 48
pounds, which is remarkably light for a 14-inch telescope. In addition, with its
f/4.6 focal ratio mirror, the Hubble UL14 telescope has an eyepiece location
that can always be reached when you are standing with both feet on the
ground (only 60" from the ground when the UL14 is pointed at zenith).
With the Hubble UL14, most NGC objects can be found from a dark sky site -
they may not be too obvious, but you can chase them down. The Hubble
UL14 will reveal the hints of color in bright emission nebula such as the Orion
Nebula and some of the brighter planetary nebulae (The Blue Snowball, The
Saturn Nebula and others), incredible detail on Jupiter and, using an H-beta
filter, a very distinct Horsehead nebula. Results will vary according to
observing conditions and other factors. The Hubble UL14 is a telescope that
can provide a lifetime of satisfying observing experiences in a less than 50-
Features of the UL14:
Exclusive Sandwich Mirror Technology: Our sandwich mirror
technology has been used to manufacture research-grade optical elements
and proven by over a half dozen years of successful applications at
research facilities such as NASA, California State Polytechnic University San
Luis Obispo, for the US Army, and in amateur telescopes around the world.
Hubble sandwich mirror’s open core and close back design not only allows
air to circulate through the mirror, but also provide the maximum structure
strength to allow a simpler mirror cell design. Our sandwich mirror will reach
thermal equilibrium up to 10 times faster than a traditional solid 14-inch
mirror and means the mirror can deliver great views even as the air around
the telescope is changing temperature.
Why is thermal equilibrium so critical? The main issue is "mirror seeing," the
turbulence seen through the eyepiece of the telescope when the air above
the mirror is different from the mirror itself. Since a sandwich mirror cools far
more rapidly than a solid mirror of the same thickness, this major source of
distortion is eliminated quickly, giving you sharp and stable views. With ever-
changing temperatures during observing or imaging, your thick and solid
mirror may never reach equilibrium, and never reach its full optical
potential. This is one of the major reasons why our lightweight-sandwich
mirror has superior optical performance in real world situations, even without
an active cooling system. (Active cooling systems, such as fans, introduce
their own problems, such as micro vibration, which may seriously degrade
the image quality.) Our sandwich mirrors reach equilibrium extremely fast,
and without any external disturbing aid.
Semi-Enhanced Optical Coatings: The Hubble UL14 primary mirror is
coated with the most recommended (by professionals) 92% Semi-Enhanced
optical coatings to assure it collects as many (while scattering as little)
photons as possible to focus it into a bright and contrast-rich image. The
optimal 92% Semi-enhanced coating has an over-coating of precision
controlled dielectric layer to maximize the reflectivity and provide excellent
chemical and mechanical protection for the mirror coating. A 96% enhanced
optical coating is applied on the secondary mirror.
Engineered Mirror Support: The UL14 has an extensively modeled and
optimized 6-point flotation system that provides more than adequate support
for the sandwich mirror. The three-point collimation system is completely
independent from the sling lateral support. It will totally eliminate the often-
found potato chip astigmatism introduced by sling belt when using the
simple 3 pivoted bolts collimation system. In a simple pivoted bolts
collimation system, the collimation of the primary mirror may cause the sling
belt to pull the mirror axially on the mirror edge, bending the mirror to a
potato-chip shape, causing annoying astigmatism.
All Metal Construction: The UL14 mechanical structures have been
extensively modeled via 3D CAD and advanced FEA to provide the optimal
structure strength and stability. Machined with Computer Numerical Control
(CNC) technology and hand fitted to assure proper fit and finish. Super
strong T6063-T3 aluminum alloy truss tubes, structure steel mirror cell and
aluminum alloy OTA and mount structure. Completed with deluxe and
environmentally friendly black powder coating, it is such a pleasure to look
at, not to mention the enjoyment to look through.
Dual-Speed 2-inch Linear Drive Crayford Focuser: The Hubble UL14
comes with a precision dual-speed, 2-inch diameter focuser. It's a beautiful
piece of precision machining that enhances the viewing experience as well
as the overall impression of a premium quality instrument you'll have with
this telescope. This focuser is robust! It is a zero-backlash "Crayford-style"
design further enhanced with modern "linear bearings" meaning you get a
rock-solid, super smooth focusing experience that can handle the weight of
even the heaviest of modern eyepieces. Its tension, the pressure on the
drawtube, is preset to a very reasonable level, but adjustable to lock heavy
equipment in place if desired. The smaller stainless steel focus control
adjusts focus at a rate 8 times finer than the larger focus wheels. This fine
adjustment allows for critical focusing during high power visual observing or
for imaging applications. The focuser has 50mm of travel distance.
