  • A Premium, Light, Compact and Portable Design - Less than half of the weight of traditional Dobsonian telescopes. Fully assembled the UP12 weighs only at about 30 pounds!
  • Outstanding Images - Premium quality, diffraction limited Newtonian optical systems will deliver stunning views of the heavens from dark sky sites
  • Advanced Optical Technology - The UP12 features Hubble lightweight thin solid mirror that cools down much faster than the regular solid mirrors
  • The UP12 f/4.5 optical system delivers bright images and features a short tube keeping the eyepiece conveniently close to the ground
  • Enhanced Coating - The 96% Enhanced Coating on both the primary and secondary mirrors.
  • A precision-machined all-aluminum construction with 8 rigid double section truss tubes and extremely strong and portable ALT bearing structure. It features a real mirror cell and mirror box for safe mirror protection, convenient storage and easy transportation
  • Modular and Compact Design: The Hubble UP12 is delivered in several preassembled modules. The entire systems can be assembled easily and quickly, as little as a few minutes.
  • Mirror cover included

Advanced Thin Solid Mirror:

Our thin solid mirror will reach thermal equilibrium much faster than a traditional thick solid mirror. It means the mirror can deliver great views even as the air around the telescope is changing temperature.

Enhanced Optical Coatings:

The Hubble UP12 primary and secondary mirrors are both coated with the 96% 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 96% enhanced coating has multiple over-coating of precision controlled dielectric layers to maximize the reflectivity and provide excellent chemical and mechanical protection for the mirror coating.

Engineered Mirror Support:

The UP12 has an optimized 6-point flotation system that provides more than adequate support for the mirror. The three-point collimation system (with two convenient front access collimation screw!) 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 Aluminum Construction:

The UP12 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 double section T6063-T3 aluminum alloy truss tubes, solid CNC aluminum cell and 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 Low Profile Light Weight Crayford Focuser:

The Hubble UP12 comes with a precision dual-speed, 2-inch diameter low profile, light weight 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 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 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.

Some counter (either real or spring load) counter weight is required to balance the scope by design. A rubber band counter weight system is provided as one simple solution. However, you may use your own real counter weight for better results.

Why would you select a Hubble UP12?

UP12 can be completely folded into an airline travel safe luggage, or a custom made backpack with only about 20kg in weight. It will be your ultimate travel scope.

The UP12 is a perfect balance between a telescope with large light-gathering capability and unbeatable portability. It will be the telescope that gets taken out to be used frequently. It will provide stunning views of the heavens and a lifetime of observing enjoyment.

The UP12 collects 44% more light than a 10" optics, allowing you to resolve significantly fainter objects and more subtle details. The UP12 has a parabolic primary with a full 12-inch diameter of optical surface, a generous 12.4" overall diameter; not an 12-inch blank with a beveled and much smaller optical surface like all other 12" telescopes in the market. It translates to about 5% more optical surface and light gathering power than any other 12" scopes in the market.

Hubble UP12 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.

With the Hubble UP12, 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 UP12 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 UP12 is a telescope that can provide a lifetime of satisfying observing experiences!
