Premium Optics with HD Concept
The optical excellence of the Conquest HDX is based on the HD concept: a perfectly balanced optical system that combines selected coatings, lenses and a finely tuned optical design. It enables 90 % light transmission for the brightest images, color fidelity for true-to-life images without color fringing and color casts for perfect identification and sharpness from edge to edge for a clear and detailed image across the entire field-of-view.
Robust and durable design
The Conquest HDX is built to last in any environment, whether it's extreme temperatures, wet conditions, or direct sunlight. Its durable, waterproof, and shockproof features are attributed to its robust mechanical design and lightweight magnesium housing. Additionally, it's covered with a protective rubber armoring that provides a perfect grip under any circumstances.
Carefully thought-out ergonomics
The carefully thought-out ergonomics enable comfortable handling during longer periods of observation thanks to the non-slip grip and the smooth and precise focusing wheel. Adjustable eyecups and lockable diopter settings ensure a customized viewing experience.
A clear view, whatever the weather
There are always exciting things to be seen in the world of nature – even in wet weather. This is why ZEISS developed LotuTec®. A coating for the lenses of binoculars and spotting scopes that enables a clear and unhindered view in all weather conditions.
ZEISS T* Coating
ZEISS T* coating is a guarantee of the brilliant, high-contrast images which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.

Our team at PlaneWave is passionate about designing exceptional telescopes so that users around the world are able to capture the most awe-inspiring astro images possible. From design to manufacture, our goal with the DeltaRho 500 was centered around creating a revolutionary wide-field telescope. The DeltaRho 500 is a Cassegrain Optical Design with the imaging train at the back of the telescope to prevent obstruction of the instrument. This offers a real advantage against prime focus designs, which can severely limit users’ ability to operate with filter wheels or large cameras. Witness the incredible breakthrough in telescope technology as the DeltaRho 500 operates at f/3 and 1537 mm focal length, which is sure to revolutionize your astrophotography.
Last, but not least, the DeltaRho 500 provides a flat field, which ensures stunning clarity from corner-to-corner images without field curvature degradation. The DeltaRho 500 offers the simplicity of single-mirror collimation, stray light control of advanced 3D printed baffles, and structural performance created through finite element analysis (FEA). DeltaRho 500 users can experience pinpoint stars edge-to-edge and a 2-degree field of view when using large 16803/4040 (52mm) size camera sensors. This field of view is over twice as large as our CDK 20! This kind of equipment allows users to experience a whole new level of wide-field imaging that can bring them closer than ever to deep space. The DeltaRho 500 allows nothing to stand in between the user and amazing astro images.
Carbon Fiber Tube Design
Minimizes thermal expansion which causes focus shift as temperature changes during an imaging session. Carbon fiber also reaches ambient temperatures quickly and is extremely lightweight and rigid to help ensure that excellent imaging data is produced.
Collimation software
Along with the included collimation mask, PlaneWave Collimation software allows for quick and easy collimation necessary to maximize the performance of a fast f-ratio optical system.
3D Printed Baffles
PlaneWave's digital 3D printing technology adds successive layers of material to our baffle systems for lightweight, precision-positioned internal stray light control to minimize vignetting and maximize image contrast.
Cooling Fans
Three fans are strategically placed on the backplate of the optical tube to ventilate through the telescope and by the primary mirror. Four additional fans on the side of the optical tube provide airflow across the primary, bringing thermal equilibrium efficiently to prevent distorted images due to temperature variations.
The fans are controlled via the PWI 4 software with the PlaneWave Series 5 Controller sold separately.
Dew Control Ready
For added dew prevention, the DR500 is internally wired with polyimide film heater pads and a temperature sensor, which is ready to be controlled with the Series 5 Controller via PWI 4 software.

The ZWO FF107 APO is a refractive astrograph with a powerful flatfield optical design which saves you from the expensive cost of a field flattener. It eliminates the trouble of calculating the back focus distance of the flattener and connecting various accessories to achieve that distance. You can just connect any possible accessories you need. As long as the target is focused, the whole optical system is perfect for imaging. This makes the whole setting up process much more convenient, and saves you time, allowing you to pay more attention to the image shooting itself.
The ZWO FF107 APO is also a nice choice for your visual observation. It fits diagonals as well as various eyepieces and can achieve a perfect focus, and can even be used to observe planets with a super-high magnification eyepiece.
The whole design of the telescope is compact and lightweight. The OTA weighs only 5.7kg, and the full package with tube rings and other accessories weighs 6.9kg. It has an aperture of 107mm. The focal ratio is f/7 and the focal length is 749mm.
The ZWO FF107 APO adopts a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness. It supports the full-frame imaging circle and has a fine spot diagram with tiny distortions of the peripheral stars. The 3″ rigid focuser comes with a new-type 360°rotator with scales and a finder base. M86, M68, M54, and M48 camera adapters are also attached, and the M48 adapter has a 2” female thread for installing filters.

Non-Illuminated Right Angle Correct Image Finderscope
The Celestron 9x50 Right Angle Correct Image (RACI) Finder is a great upgrade to the standard finderscopes included with many Schmidt-Cassegrain telescopes. The generous 50mm aperture produces bright, sharp images with a magnification of 9x and a five-degree apparent field of view. Meanwhile, the right-angle, correct-image design keeps objects right-side-up and correctly oriented left-to-right, making it easier to find objects and track them as they drift through the field of view. You can rotate the eyepiece module left or right to find the perfect viewing angle based on your setup.
The double-crosshair reticle etched in the eyepiece makes it easy to center an object, whether you are aligning your computerized telescope or finding deep-sky objects on your own. The reticle can be focused separately from the finder itself.
The Celestron 9x50 RACI Finder comes with a sturdy bracket consisting of two rings and an integrated dovetail. The oversized thumbscrews make adjusting the finder's alignment easy. The dovetail allows for easy attachment to and removal from most Schmidt-Cassegrain and EdgeHD optical tube assemblies without affecting the finderscope's alignment. The eyepiece also features an attachment point for an aftermarket M8x1.25 thread-in illuminator.

Hubble UL12 – 12" Lightweight Reflector Telescope
Hubble UP12 – An Ultra-Portable 12" Dobsonian Telescope
The Hubble UP12 is a premium 12-inch Dobsonian designed for observers who want serious optical performance in an exceptionally compact and travel-friendly form. Weighing just 14.5 kg) fully assembled, the UP12 delivers true large-aperture performance in a package that can be transported, stored, and deployed with ease.
Once disassembled, the UP12 can be packed into airline-approved luggage, making it one of the most portable 12-inch telescopes available. This is a genuine “take anywhere” instrument for dark-sky trips, remote expeditions, and observers who value performance without bulk.
Light, Compact and Truly Portable
The UP12 is less than half the weight of a traditional 12-inch Dobsonian. Its modular construction allows the entire system to be assembled in just a few minutes, with no heavy components and no complex setup.
All major structural elements are made from precision-machined aluminium alloy, providing excellent rigidity while keeping weight to an absolute minimum. The result is a telescope that feels effortless to transport, yet remains mechanically stable at high magnifications.
Optical Performance
The UP12 uses a premium parabolic primary mirror, individually tested and finished to achieve diffraction-limited performance (Strehl 0.95+). The secondary mirror is specified to 1/10 wave or better, delivering high contrast and sharp stellar images across the field.
Both mirrors receive 96% enhanced reflective coatings, maximising light throughput and reducing scatter. From a dark sky site, the UP12 is capable of revealing most NGC objects, subtle structure in bright nebulae, fine planetary detail on Jupiter and Saturn, and even challenging targets such as the Horsehead Nebula when used with appropriate filters.
A Perfect Balance of Power and Portability
The UP12 gathers around 44% more light than a 10-inch telescope, yet remains dramatically smaller and lighter than traditional 12-inch designs. Its full 12-inch optical surface (with a generous 12.4-inch overall diameter) provides slightly more true light-gathering area than many mass-produced 12-inch mirrors.
This balance makes the UP12 a telescope that actually gets used. It is large enough to deliver meaningful deep-sky performance, yet portable enough to be taken out frequently without hesitation.

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.

Hubble UL24 – A Lightweight 24" Dobsonian Telescope
The Hubble UL24 is a made-to-order 24-inch Dobsonian telescope, designed for experienced observers who want truly extreme aperture without sacrificing transportability.
With a huge 24-inch primary mirror, the UL24 delivers around nine times the light grasp of an 8-inch telescope and four times that of a 12-inch, revealing ultra-faint galaxies, subtle nebular structure, and fine detail in planetary nebulae that smaller instruments simply cannot reach.
Light, Strong, and Surprisingly Portable
The UL24 features a precision-machined all-metal construction with eight rigid aluminium truss tubes and an extremely strong folding altitude bearing structure. Despite its massive aperture, the complete telescope weighs only around 70 kg, making it dramatically lighter than traditional 24-inch Dobsonians.
A real mirror box protects the primary mirror during transport, while the modular design allows the telescope to be broken down into manageable components for storage and travel. The heaviest single component is the primary mirror at around 30 kg, allowing one person to realistically transport the system to dark-sky locations.
Optical Performance
At the heart of the UL24 is a premium parabolic primary mirror with a full 24-inch optical surface and an overall diameter of 24.4 inches. This provides around 4% more true optical area than many other 24-inch designs that use undersized optical surfaces.
Each mirror is individually tested and finished to achieve diffraction-limited performance, with a Strehl ratio of 0.95+ for the primary and 1/10 wave or better for the secondary. Both mirrors receive 96% enhanced reflective coatings, maximising light throughput and contrast while reducing scatter.
The fast f/3.3 focal ratio keeps the eyepiece height to just 1955 mm at zenith, allowing most observers to use the telescope without a ladder while still enjoying extreme aperture.
Choose Your Telescope Control
The UL24 can be customised to suit your observing style. You can use it fully manually, or opt for Guided Push-To or Automatic Go-To systems.
Manual Mode
Even without electronics, the UL24 remains a highly refined Dobsonian with smooth, stable motion and precise balance. Manual observing delivers the classic deep-sky experience at a scale few observers ever reach.
Guided Push-To Version
The Guided Push-To version uses the SkyHub2 digital setting circle system, providing accurate real-time positioning without motorised tracking. High-resolution encoders on both axes feed live position data into compatible planetarium software.
Alignment is quick and intuitive using one- or two-star alignment. The system works with SkySafari, Stellarium, Cartes du Ciel, TheSky, and other ASCOM-compatible software on Windows, macOS, Android, and iOS devices.
Power consumption is extremely low, allowing up to 100 hours of operation from a standard USB power bank. Both WiFi and Bluetooth are supported.
Automatic Go-To Version
The Go-To version adds fully motorised pointing and tracking for hands-free observing. A smart hand controller with a 30,000-object database supports multi-star alignment for highly accurate pointing.
Built-in encoders and a real-time clock maintain accurate sidereal, lunar, and solar tracking. The system can be controlled via WiFi or Bluetooth using SkySafari, Stellarium, or ASCOM/INDI-compatible software on Windows, macOS, Linux, iOS, or Android.
Adjustable slew and guide speeds, spiral search, and park/unpark functionality ensure smooth, precise operation during long observing sessions.

Hubble UL20 – A Lightweight 20" Dobsonian Telescope
The Hubble UL20 is a made-to-order 20-inch Dobsonian telescope designed for observers who want truly extreme aperture without the bulk and weight of traditional large Dobsonians.
With its enormous 20-inch primary mirror, the UL20 gathers over six times more light than an 8-inch telescope, and almost three times the light grasp of a 12-inch, revealing galaxies, nebulae, and fine structure at a level normally reserved for permanent observatory installations.
A Premium, Light, Compact and Portable Design
Despite its size, the UL20 is engineered to remain practical and transportable. The precision-machined all-metal truss construction delivers exceptional rigidity while keeping overall weight to around half that of traditional 20-inch Dobsonians.
The modular truss design allows the telescope to be broken down for transport, while the reinforced mirror box protects the primary mirror during storage and travel. This makes the UL20 a genuine “portable observatory” for dedicated deep-sky observers.
Optical Performance
At the heart of the UL20 is a premium parabolic primary mirror, individually tested and finished to achieve diffraction-limited performance (Strehl 0.95+). The secondary mirror is specified to 1/10 wave or better, ensuring excellent contrast and pinpoint stellar images across the field.
Both mirrors receive 96% enhanced reflective coatings, maximising light throughput while reducing scatter. This results in breathtaking deep-sky views, extremely faint object detection, and exceptional planetary performance even at very high magnifications.
Choose Your Telescope Control
The UL20 can be customised to suit your observing style. You can use it fully manually, or opt for Guided Push-To or Automatic Go-To systems.
Manual Mode
Even without electronics, the UL20 remains a precision Dobsonian with smooth, stable bearings and a well-balanced truss structure. This allows for classic hands-on observing with direct control and intuitive sky navigation.
Guided Push-To Version
The UL20 Guided Push-To version features the SkyHub2 digital setting circle system, providing accurate real-time telescope positioning without motorised tracking. High-resolution 8192 PPR encoders on both axes continuously update your telescope’s position in compatible planetarium software.
-
Fast one-star alignment, with optional two-star alignment for higher accuracy
-
Compatible with SkySafari, Stellarium, Cartes du Ciel, TheSky, and other ASCOM software

Why choose f/4.2?
-
Sharper images with almost 50% less coma than f/3.7
-
Smaller central obstruction (3.5" secondary vs 4.0" on f/3.7)
-
Easier to achieve perfect collimation
-
Better suited for high-magnification lunar and planetary observing
-
A coma corrector is helpful but not essential for many users
Why choose f/3.3 or f/3.7?
-
No ladder required at all for f/3.3; only a small step may be needed for f/4.2 near zenith
-
Extremely wide true field of view, especially with f/3.3
-
Ideal for sweeping large nebulae and rich Milky Way fields
All three versions deliver extraordinary performance. A coma corrector is strongly recommended for the UL20 f/3.3, while the f/4.2 prioritises optical cleanliness and ease of use.

Hubble UL16 – 16" Lightweight Reflector Telescope
The Hubble UL16 is a made-to-order 16-inch Dobsonian telescope built for serious visual observers who want maximum aperture without sacrificing portability. Combining advanced mirror technology with precision engineering, the UL16 delivers exceptional deep-sky and planetary performance in a surprisingly manageable package.
Optical Performance
At the heart of the UL16 is a full 16-inch parabolic primary mirror featuring Hubble’s exclusive Sandwich Mirror Technology. This lightweight yet rigid design achieves diffraction-limited performance (Strehl 0.95+) while reaching thermal equilibrium up to ten times faster than traditional solid mirrors. Faster cooldown means reduced mirror seeing and sharper, steadier views sooner after setup.
Both primary and secondary mirrors feature 96% enhanced reflective coatings, maximising light throughput and contrast while minimising scatter. The result is brighter galaxies, improved nebular detail, and high-contrast planetary views even at high magnification.
Engineered for Precision
A carefully designed flotation mirror support system combined with independent collimation ensures the primary mirror is evenly supported, minimising astigmatism and maintaining optical accuracy across the sky. The UL16’s robust construction uses CNC-machined aluminium structural components and a steel mirror cell, providing excellent rigidity without unnecessary mass.
Smooth, Accurate Focusing
The UL16 is equipped with a 2-inch dual-speed Crayford focuser featuring linear bearings for smooth, backlash-free operation. Fine focus control allows precise adjustment at high magnifications and works seamlessly with heavy eyepieces or imaging accessories.
Big Aperture, Thoughtful Portability
Despite its impressive aperture, the UL16 is designed with transport in mind. The truss-tube construction breaks down easily for travel, while the fast focal ratios keep eyepiece height within a comfortable range. Whether observing from your backyard or transporting to dark skies, the UL16 balances power with practicality.
Unmatched Observing Potential
With significantly more light-gathering power than a 14-inch telescope, the UL16 reveals faint galaxies, subtle nebular structure, and fine planetary detail that smaller instruments simply cannot match. From resolving globular clusters to tracking delicate dust lanes in distant galaxies, the UL16 is built for observers who want to go deeper.
Push-To and Go-To Options
Guided Push-To Version
The UL16 Guided Push-To version features the SkyHub2 digital setting circle system, providing accurate real-time positioning without motorised tracking. High-resolution (8192 PPR) encoders on both axes continuously update your telescope’s position in compatible planetarium software.

Hubble UL14g – 14" Lightweight Reflector Telescope
The Hubble UL14g is a premium 14-inch Dobsonian telescope designed for serious visual observers who want substantial aperture in a system that remains genuinely portable. Combining advanced mirror technology with precision-machined construction, the UL14g delivers impressive deep-sky and planetary performance in a compact, travel-friendly design.
Optical Performance
At the heart of the UL14g is a full 14-inch parabolic primary mirror featuring Hubble’s exclusive Sandwich Mirror Technology. This lightweight yet rigid design achieves diffraction-limited performance (Strehl 0.95+) while reaching thermal equilibrium up to ten times faster than traditional solid mirrors. Faster cooldown means reduced mirror seeing and sharper, more stable views shortly after setup.
Both primary and secondary mirrors feature 96% enhanced reflective coatings, maximising light throughput and contrast while minimising scatter. This results in brighter galaxies, improved nebular structure, and high-contrast planetary detail even at high magnifications.
Engineered for Precision
The UL14g uses a real mirror box and precision flotation mirror support system to evenly distribute load across the primary mirror, minimising deformation and preserving optical accuracy across the sky. The structure is built from CNC-machined aluminium components with a steel mirror cell, providing excellent rigidity while remaining exceptionally lightweight.
Eight rigid truss tubes ensure stable collimation, while the large altitude bearings provide smooth and predictable motion during tracking.
Smooth, Accurate Focusing
The UL14g is equipped with a 2-inch dual-speed Crayford focuser with linear bearings, delivering smooth, backlash-free focusing. Fine focus control makes it easy to achieve critical focus at high power and supports heavy wide-field eyepieces without flex or slippage.
Big Aperture, Exceptional Portability
Despite its 14-inch aperture, the UL14g is remarkably easy to transport and set up. The modular truss-tube design breaks down into compact components that can be assembled in just a few minutes without tools. The heaviest single component is the primary mirror, weighing around 7 kg, making solo transport realistic for most observers.
With its fast f/4.6 focal ratio, the eyepiece height remains accessible at all times — just 60 inches at zenith — allowing comfortable observing with both feet on the ground.
Unmatched Observing Potential
The UL14g collects approximately 36% more light than a 12-inch telescope and nearly double that of a 10-inch, allowing significantly fainter objects and finer details to be resolved. From dense globular clusters to delicate dust lanes in distant galaxies, the UL14g reveals a level of structure that smaller instruments simply cannot match.
From dark-sky sites, most NGC objects are within reach. Bright emission nebulae show subtle hints of colour, planetary nebulae display internal structure, and Jupiter reveals fine banding and atmospheric detail. With an H-beta filter, even challenging targets like the Horsehead Nebula become achievable under good conditions.
The UL14g strikes a rare balance between serious aperture and true portability, making it a telescope that gets used often, not one that stays in storage.

Get the most out of your Celestron Rowe-Ackermann Schmidt Astrograph 11, even under light-polluted skies, with this Light Pollution Imaging Filter, custom-designed for the RASA. No matter which camera you use, this filter’s generous 68 mm clear aperture allows it to easily accommodate today’s largest sensors. Utilizing a machined aluminum housing and Schott B270 glass, the filter replaces the RASA’s clear optical window so the RASA’s optical performance is unaltered.
Remove Light Pollution While Keeping Your Images Bright
Light pollution limits how much of the night sky we can see and photograph. When imaging with a color camera in light polluted areas, skyglow degrades image quality. Light pollution filters help to selectively block light emitted from common streetlights and other ambient lighting. But most light pollution filters greatly compromise the total light throughput, causing dim images, and negatively impact the color balance, causing images to appear too green or blue.
The Light Pollution Imaging Filter for RASA “surgically” removes unwanted light pollution while preserving as much of the useful spectrum as possible. That means you’ll still retain over 90 percent of the light captured by your telescope at many wavelengths.
Unlike other light pollution suppression filters, the Celestron LP Imaging Filter for RASA maintains a relatively neutral color balance so you can bring out subtle color in galaxies and other faint deep sky objects. Multiple layers of specially-formulated dielectric coatings provide the desired transmission, while anti-reflective coatings minimize star halos and internal reflections.
Also included is a clear plastic case to protect the filter when not in use
