5.1″ Reflector Telescope Optronic 130ST EQ with Fast f/5 Optics

Description

Product Overview

The Optronic 130ST EQ is a compact, portable 5‑inch (130 mm) Newtonian reflector telescope designed for both novice astronomers and seasoned hobbyists who value ease of use without sacrificing optical performance. Its 5‑inch primary mirror gathers a substantial amount of light, delivering bright, high‑contrast images of lunar craters, planetary details, and brighter deep‑sky objects such as nebulae and star clusters. The fast f/5 focal ratio provides a wide field of view, making it ideal for scanning large swaths of the night sky and locating objects quickly.

Constructed from durable aluminum alloy, the optical tube is lightweight yet rigid, reducing flexure during transport and while tracking objects. The telescope arrives fully assembled, with a total weight of just 28 lb (12.7 kg), allowing easy setup on the included adjustable tripod. The equatorial mount features smooth, low‑friction bearings and a slow‑motion control knob that enables precise manual tracking of celestial objects as they drift across the sky. This combination of sturdy mechanics and high‑quality optics ensures reliable performance night after night.

Included accessories enhance the observing experience: two 1.25‑inch Plössl eyepieces (25 mm and 10 mm) provide low and high magnification options, a smartphone camera adapter enables astrophotography with a mobile device, and a collimation cap assists in maintaining optimal optical alignment. Additional items such as the DeepMap 600 and MoonMap 260 charts help users identify targets quickly, while the sturdy tripod base offers adjustable height for comfortable viewing at various angles.

Usage

The 130ST EQ excels in a variety of observing environments. Its compact size and moderate weight make it perfect for backyard astronomy sessions, weekend camping trips, or school science programs where portability is essential. The fast f/5 optics allow users to locate and view bright deep‑sky objects with relatively short exposure times, which is especially beneficial in areas with moderate light pollution.

Because the telescope includes an equatorial mount, it is well suited for tracking objects that move across the sky due to Earth’s rotation. The slow‑motion control knob provides fine adjustments, enabling smooth tracking of planets, the Moon, and extended objects like the Orion Nebula. Beginners will appreciate the intuitive polar alignment process, while more experienced users can take advantage of the mount’s stability for longer observation sessions.

The included smartphone adapter opens the door to casual astrophotography. Users can attach their phone to the eyepiece, capture images of lunar detail, planetary bands, or even wide‑field shots of star clusters. The provided sky maps and collimation tools further simplify the learning curve, making the telescope a versatile tool for educational outreach, family outings, and personal exploration of the night sky.

FAQ

What is the best way to align the equatorial mount?

Begin by setting up the tripod on a stable surface and leveling the mount. Use the polar scope to locate the North Celestial Pole (or South, depending on your hemisphere) and align the mount’s latitude dial to your geographic latitude. Once the mount is roughly aligned, fine‑tune using the slow‑motion controls while tracking a bright star to ensure smooth movement.

Can I use this telescope for astrophotography?

Yes. The included smartphone adapter allows you to attach a mobile device to the eyepiece and capture images of the Moon, planets, and bright deep‑sky objects. For longer exposure astrophotography, you may wish to add a tracking motor or use a dedicated camera adapter, but the basic setup works well for casual imaging and sharing on social media.

How do I collimate the telescope?

Collimation ensures the mirrors are correctly aligned for optimal image quality. Use the collimation cap provided in the accessory kit: insert it into the focuser, look through the eyepiece, and adjust the primary mirror screws until the reflected circles are concentric. Re‑check after transport or any major adjustments, as the alignment can shift.

Is this telescope suitable for children?

The 130ST EQ is designed with a user‑friendly assembly and intuitive controls, making it appropriate for older children and families. Supervision is recommended for younger users, especially when handling the mount and adjusting the tripod. The included educational materials, such as sky maps, help engage younger astronomers and foster a love of stargazing.

What warranty does Optronic provide?

Optronic Technologies offers a one‑year limited warranty covering manufacturing defects in the optical tube, mount, and included accessories. The warranty does not cover damage caused by misuse or accidental impact. For warranty claims, contact Optronic customer service with your purchase details, and they will guide you through the repair or replacement process.
