Hubble UL32 – 32" Lightweight Reflector Telescope

The Hubble UL32sg is a flagship 32-inch Dobsonian telescope designed for serious deep-sky observers, research-grade visual work, and advanced EAA applications. With a massive 32-inch primary mirror, the UL32sg delivers 16 times the light grasp of an 8-inch telescope and four times that of a 16-inch, revealing galaxies, nebulae, and fine structure at a level few instruments on Earth can match.

Despite its extraordinary aperture, the UL32sg is engineered to remain as compact and transportable as possible for its class. Fully assembled, the telescope weighs around 150 kg and features a modular, all-metal construction with sectional truss tubes and a folding altitude bearing structure. A real mirror box provides safe protection for the primary mirror during transport and storage.

Light, Strong, Compact and Still Portable

The UL32sg is built using precision-machined aluminium alloy components, extensively modelled with CAD and FEA to optimise structural rigidity while minimising weight. Eight rigid sectional truss tubes ensure excellent stiffness and collimation stability, even at extreme elevations.

While the UL32sg is not a casual backyard instrument, it remains one of the most compact and practical 32-inch class telescopes available, capable of being transported and assembled by a small team for dark-sky expeditions, observatories, and research installations.

Revolutionary Smart Go-To System

The UL32sg is supplied exclusively in a Smart Go-To configuration, built around the state-of-the-art OnStep control system. This advanced platform combines fully motorised Go-To, high-resolution encoders, and a revolutionary plate-solving smart finder for unmatched pointing accuracy.

Using the system is simple: select a target via the smart hand controller or third-party software such as SkySafari or Stellarium, then with a single button press the telescope captures an image, plate-solves its position, and automatically refines its pointing until the target is perfectly centred.

The system supports automated star alignment, automated “Star Shows” such as Messier Marathons, intelligent routing to reduce slewing time by 30–50%, and full EAA live stacking for electronically assisted observing.

Connectivity includes built-in WiFi and Bluetooth, INDI and ASCOM drivers, real-time clock, spiral search, park/unpark, and full sidereal, lunar, and solar tracking rates. Control is available via smart hand controller, desktop software, or mobile apps on Windows, macOS, Linux, iOS, and Android.

Exclusive Sandwich Mirror Technology

The UL32sg uses a lightweight sandwich primary mirror designed to reach thermal equilibrium far faster than traditional solid mirrors. Rapid cooling dramatically reduces mirror seeing and internal turbulence, allowing the telescope to achieve its full optical potential much sooner in real-world conditions.

Unlike thick solid mirrors that may never stabilise during changing temperatures, the sandwich design delivers sharp, stable images without the need for active cooling systems, avoiding vibration and mechanical complexity.

Enhanced Optical Coatings

Both primary and secondary mirrors receive 96% enhanced dielectric coatings with multiple precision-controlled layers. These coatings maximise reflectivity, reduce scatter, and provide excellent chemical and mechanical durability, delivering bright, high-contrast images even at extreme magnifications.

Real Mirror Cell in a Real Mirror Box

The UL32sg features a fully engineered 27-point flotation mirror cell with sling and 90-degree pivoting lateral supports. This system prevents mirror deformation and eliminates astigmatism commonly caused by simpler collimation designs.

The independent three-point rod-end collimation system allows precise adjustment without stressing the mirror edge, maintaining optical integrity under all observing orientations.

Dual-Speed 2" Linear Bearing Crayford Focuser

The UL32sg is fitted with a precision 2-inch dual-speed linear bearing Crayford focuser, capable of handling heavy modern eyepieces and imaging equipment. The fine focus control provides ten times finer adjustment for critical focusing at high power or during EAA use, with approximately 50 mm of travel.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

Capturing the most stunning astrophotographs possible is something our team is passionate about. From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 20″ telescope was centered around performance and ease of use. The Planewave CDK20 f/7.7 OTA is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK20 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK20 is an exceptional diffraction-limited telescope. CDK20 users can experience pinpoint stars edge-to-edge and a 45 x 45 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!

Our largest refractor, the APO250VT F/8.8 allows the observer to immerse themselves in the beauty of space. This observatory class instrument provides the best visual experience that TEC has to offer.

• The APO250VT F/8.8 features an air-spaced apochromatic-triplet objective with a Fluorite (CaF₂) middle element, resulting in color correction that is optimized for visual use and imaging. This air-spaced triplet design in combination with multi-layer coatings on all surfaces of the objective ensure maximal light transmission.
• The objective is housed in an titanium cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
• The optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation – after the scope leaves TEC, no adjustment is required.
• Further, the crisp all white assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color out of this compact and timeless design.
• Each APO250VT F/8.8 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments’ largest rotating focuser with coarse and fine focusing 9:1 Planetary Reduction Assembly.
• The 2” locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity.
• Includes precision adjustable Tube Rings.
• Able to accommodate a wide variety of eyepieces.
• Recommended to be paired with a high capacity load mount and a stationary observation station.

In classic refractor fashion, the TEC APO250VT F/8.8 is a no compromise, no frills design that lets the wonders of nature speak for themselves. Please know that ALL PRICES AND AVAILABILITY ARE SUBJECT TO CHANGE WITHOUT NOTICE

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and we then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach Yuri’s expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferomerical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.

The venerable Dobsonian reflector design has recently undergone some important upgrades and improvements: Skywatcher is pleased to introduce the all-new Collapsible Dobsonian complete with Crayford focuser – the ultimate in large aperture portability and performance.

This elegant truss tube design was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the Skywatcher Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening!

The bearing system has been redesigned as well. The new Skywatcher Collapsible Dobsonians feature buttery smooth azimuth bearings. Even the twelve-inch model can be rotated with just the push of a finger. Like our traditional Dobsonians, the new Collapsible Dobsonians feature Skywatcher’s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the telescope.

To top it off, all of the new Collapsible Dobsonians are shipping with ultra smooth Crayford focusers.
