Key Features
1. 150 mm Achromatic Refractor Lens for Sharp, Bright Visuals
The telescope’s fully coated 150 mm (6-inch) achromatic lens gathers ample light to provide bright, crisp, and high-contrast images. It handles planetary detail and deep-sky objects with clarity, making it an ideal choice for both near and far celestial targets. Unlike reflectors, the refractor design eliminates the need for frequent alignment, ensuring consistent performance and maintenance-free operation. From Jupiter’s moons to the Andromeda Galaxy, your views will be vivid and impressively detailed.
2. EQ‑4 German Equatorial Mount for Precision Tracking
Equipped with a stable and smooth EQ‑4 equatorial mount, this telescope allows you to follow the motion of celestial objects as the Earth rotates. With slow-motion control cables for both the Right Ascension and Declination axes, tracking planets, stars, and the Moon becomes fluid and intuitive. The mount’s strong counterweight system and upgrade-ready design also make it suitable for beginner astrophotography. You can even add a motorized drive in the future as your passion grows.
3. Interchangeable Eyepieces (25 mm & 10 mm) for Flexible Magnification
This telescope includes two 1.25″ eyepieces—a 25 mm low-power eyepiece for wide-angle exploration (36×) and a 10 mm high-power eyepiece for zoomed-in planetary and lunar views (90×). These two options let you enjoy everything from broad star fields and deep-sky objects to fine details on Jupiter and Saturn. Both eyepieces are built with coated optics to enhance contrast and reduce glare, giving you a clean, immersive view every time you observe.
4. 6×30 Finderscope and Smooth Focusing Mechanism
The 6×30 optical finderscope offers a wide, magnified field of view to make locating objects in the night sky faster and more accurate. Once aligned with the main tube, the finderscope becomes an indispensable tool for quick star-hopping and celestial navigation. Meanwhile, the telescope’s large focusing knob provides smooth, precise adjustments, allowing you to achieve razor-sharp clarity whether you’re observing the Moon’s surface or zooming in on a distant star.
5. Heavy-Duty Tripod with Reinforced Accessory Tray
Built with a sturdy adjustable steel tripod, this telescope offers solid support during extended viewing sessions. Its central accessory tray improves stability while providing easy access to your eyepieces, filters, and observation notes. The tripod legs are height-adjustable, accommodating different user preferences and terrains. Whether you’re on a balcony, terrace, or open hillside, the tripod ensures minimal vibrations and a rock-steady view—even at higher magnifications.
Why You’ll Love the Dr. Mady 150 mm EQ‑4 Refractor Telescope
1. Bright, High-Contrast Views with Zero Collimation Hassles
With its larger 150 mm refractor lens, this telescope delivers exceptionally clear and detailed visuals of celestial objects without the maintenance worries of mirror-based designs. You’ll enjoy razor-sharp views of the Moon’s craters, Jupiter’s cloud bands, and even faint galaxies—all with rich contrast and minimal color distortion. And since refractors don’t need regular collimation, you can focus more on observing and less on adjusting, making it a favorite for users who want top-notch visuals and convenience in one package.
2. Smooth Manual Tracking That Supports Future Upgrades
The EQ‑4 equatorial mount makes following stars and planets feel natural and precise. With dual slow-motion controls and a balanced counterweight system, tracking becomes steady even during long sessions. Whether you’re watching Saturn drift across the eyepiece or planning a motorized upgrade for astrophotography, this mount is built to scale with your growing astronomy skills—providing both control and flexibility from day one.
3. Wide-Angle Sweeps and Close-Up Zooms in One Setup
Thanks to the included 25 mm and 10 mm eyepieces, you can switch effortlessly between panoramic sky views and zoomed-in planetary detail without needing extra equipment. Use the 25 mm for broad star fields and deep-sky objects, then pop in the 10 mm to see the rings of Saturn or lunar valleys up close. Whether you’re exploring galaxies or simply admiring the Moon, this dual-eyepiece setup keeps things fun, flexible, and beginner-friendly.
4. Beginner-Friendly Operation with Pro-Level Features
Despite its serious optical power, this telescope is surprisingly approachable. From the 6×30 finderscope that helps you lock onto stars quickly to the large focusing knob that sharpens your image with ease, every part is designed to be intuitive. Whether you’re new to astronomy or returning after years, you’ll feel right at home using this scope without needing a steep learning curve or complicated setup.
5. Durable Build That Travels from Backyard to Open Skies
Built on a heavy-duty steel tripod and reinforced with an integrated accessory tray, this telescope is stable enough for high-magnification viewing and portable enough to pack up for dark-sky trips. Whether you’re hosting a backyard star party or heading to a hilltop to catch a meteor shower, it’s rugged enough to handle transport and weather, making it your trusted companion for countless nights under the stars.
How to Use
1. Set Up the Tripod and EQ4 Mount
Place the sturdy tripod on solid, level ground. Attach the EQ4 equatorial mount securely, tightening all knobs by hand. The heavy-duty design supports the large refractor tube and ensures stable viewing.
2. Mount the 150 mm Optical Tube
Carefully insert the 150 mm refractor tube into the dovetail saddle on the mount. Tighten the clamp so the tube stays firmly in place, without typical shifting when pointed in different directions.
3. Align the 6×30 Finder Scope
During the day, pick a distant object—like a chimney or tower. Center it in the eyepiece view, then adjust the finder scope until that same object is held in the crosshairs. This alignment makes locating stars and planets much easier at night.
4. Choose Eyepieces and Focus
Start with the 25 mm eyepiece for scenic views and switch to the 10 mm for close-ups of planets or lunar details. Optional Barlow lenses double your magnification. Use the smooth rack-and-pinion focuser to bring objects into crisp clarity.
5. Track the Sky Using the Equatorial Mount
Polar align the EQ4 mount using Polaris (in the Northern Hemisphere). Then use the slow-motion control knobs on the RA and DEC axes to follow stars or planets as they move through the sky.
How to Take Care
1. Clean the Objective Lens Gently
Use an air blower to remove dust, then softly wipe the large front lens with a microfiber cloth. Avoid rough materials or fingerprints to preserve the high-quality lens coatings.
2. Prevent Moisture Buildup
If dew or condensation appears during use, let the telescope dry indoors before storing. Moisture can damage optics over time, so avoid closing the telescope damp.
3. Store Carefully in a Proper Case
After stargazing, place the lens cover and store the tube, mount, and eyepieces in a padded case or dry cabinet. This helps protect sensitive parts from dust, bumps, and temperature changes.
4. Check Mount Balance Regularly
Ensure the tube doesn’t swing or tilt when you loosen the clutch. If needed, adjust the balance blocks or tube position to maintain smooth balance before each session.
5. Keep It in a Cool, Clean Space
Store the telescope away from direct sunlight, high humidity, or dust. Avoid storing it in damp basements or near radiators—clean air and neutral temperatures extend its lifespan.
Safety Tips
1. Never Observe the Sun Without Protection
Only use this telescope with a full-aperture solar filter securely fitted to the front. Never look at the Sun without proper protection—it can permanently damage your eyes and the telescope.
2. Use Only on Firm, Stable Surfaces
Set up on level terrain like concrete or a patio. Avoid grass hills or uneven ground, which may cause wobbling or accidental tipping.
3. Supervise Anyone Using the Telescope
This is a precision optical instrument, not a toy. Beginners or younger users should always operate it under supervision to prevent misuse or damage.
4. Do Not Open Optical Components
The internal lens alignment is precise. Never disassemble the tube or focuser—incorrect adjustments ruin the image quality and may void the warranty.
5. Avoid Exposure to Extreme Elements
Do not use in heavy rain, wind, or sandstorms. Protect from dirt and debris, and always allow time to dry and clean before storing after outdoor sessions.
