Explore Scientific 150/750 EQ-3 Newtonian Reflector Telescope

Explore deep space in high definition with the Explore Scientific 150/750 EQ-3 Reflector Telescope. Featuring a substantial 150mm (6-inch) parabolic primary mirror and a fast f/5 focal ratio, this Newtonian reflector gathers 459x more light than the human eye, making distant nebulae, star clusters, and galaxies glow with remarkable clarity.

Built for both deep-sky visual observing and astrophotography, the optical tube comes equipped with a heavy-duty 2.0-inch draw-tube focuser (with a 1.25" adapter) ready for prime focus DSLR camera attachment. Supported by an EXOS EQ3 German Equatorial Mount with dual flexible slow-motion controls, this telescope makes tracking targets across the night sky smooth and precise.

Detailed Features & Technical Highlights

1. Parabolic Primary Mirror & 55mm Oversized Secondary Mirror

Unlike entry-level spherical reflectors that suffer from optical distortion, the Explore Scientific 150/750 features a precision-ground parabolic primary mirror that focuses all light wavelengths to a single point for pinpoint-sharp views. Paired with a 55mm secondary mirror, it ensures maximum light throughput and edge-to-edge field illumination.

2. Fast f/5 Optics for Astrophotography

With a 750mm focal length (f/5), this telescope provides an optimal wide field of view. Its fast aperture ratio shortens exposure times for deep-sky astrophotography, allowing astrophotographers to capture rich detail in targets like the Orion Nebula, Ring Nebula, and Whirlpool Galaxy.

3. Dual-Format 2.0" Focuser (1.25" Adapter Included)

Equipped with a sturdy 2.0-inch focuser, this setup accepts 2.0" wide-field eyepieces and accessories for immersive wide-field scanning. The included 2.0" to 1.25" reducer adapter features integrated camera threads (M42), allowing direct attachment of DSLR cameras via a T-ring for prime focus imaging.

4. EXOS EQ3 German Equatorial Mount & Steel Tripod

The included EQ-3 German Equatorial Mount allows simple polar alignment to counteract Earth's rotation. Using two flexible gearing shafts, observers can keep celestial targets centered in the eyepiece effortlessly. Includes a height-adjustable steel tripod, dual counterweights (for precise balance), and an accessory tray.
