Hubble UL14 Premium Dobsonian telescope is optimized to offer you high-quality, large-aperture telescopes designed 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 across the globe!
-A Premium, Light, Compact and Portable Design: About half the weight of traditional Dobsonian telescopes
-Outstanding Images: Premium quality, diffraction limited (with Strehl 0.95+) Newtonian optical systems will deliver stunning views of the heavens from dark sky sites
-Light, Strong, Compact and Extremely Portable: The Hubble UL14 features a precision-machined all-metal construction. Fully assembled the UL14 weighs at about 48 pounds. It has 8 rigid truss tubes and extremely strong and portable folding ALT bearing structure. It features a real box for safe and convenient mirror protection, storage and transportation
-Exclusive Optical Technology: The UL14 features Hubble lightweight sandwich mirror with an optimized thermal design that cools up to 10 times faster than the regular solid mirrors
-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, which is about 5% more optical surface and light gathering than any other 14" scopes in the market.
-Semi-Enhanced Coating on the Primary Mirror: The most recommended (by professionals) 92% Semi-Enhanced Coating on the primary mirror and 96% Enhanced coating on the secondary mirror.
-Modular and Compact Design: The Hubble UL14 is delivered in several preassembled modules. The entire systems can be assembled easily and quickly, as little as a few minutes.
$947.50 deposit at the order time, rest plus S&H before delivery. The delivery time is about 30-60 days.
Features of the UL14:
Exclusive Sandwich Mirror Technology: The UL14 features Hubble's lightweight sandwich mirror with an optimized thermal design that cools up to 10 times faster than regular solid mirrors. Our sandwich mirror technology is used in research-grade optical applications by NASA, California State Polytechnic University San Luis Obispo, the US Army, as well as in amateur telescopes around the world.
Hubble sandwich mirrors 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.
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. 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 brass focus control adjusts focus at a rate 10 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.
State-of-the-art Wireless Digital Setting Circle option:
Breakthrough Wireless Digital Setting Circle with revolutionary high resolution, lower power consumption ball bearing encoders at an inconceivable special price of $149 when ordered with UL14. Combined with Sky Safari (on Android), it is the most powerful wireless Digital Setting Circle in the world, at inconceivable price. Skysafari (Pro) features 15.3 million stars, 740,000 galaxies, and 550,000 solar system objects - including all the comets and asteroids ever discovered.
State-of-the-art GoTo option:
The professional grade SiTech controller combined with the revolutionary SkySafari will more than double your enjoyment and fun with the Heavens; you simply touch the sky. It is the most powerful GOTO system at an extremely affordable price; there is no comparison, period.
