Description
Observe detailed lunar crater formations and split bright binary stars with the Skywatcher N 130/900 Explorer EQ-2 Telescope manual equatorial reflector system. Designed with an f/6.9 focal ratio, this 130mm (5.12 in) aperture telescope features a 900mm focal length, delivering 0.89 arcseconds Dawes resolving power and reaching magnitude 13.3 for high-contrast planetary and deep-sky exploration.
The Skywatcher N 130/900 Explorer EQ-2 Telescope incorporates a spherical primary mirror made from borosilicate optical glass, coated with 94% reflective aluminum and a protective silicon dioxide (SiO2) layer. Its 840mm solid metal tube features an internal light path, a minimal 24% secondary obstruction, and a 1.25-inch rack-and-pinion focuser. Mounted on an EQ-2 manual German equatorial mount with slow-motion cables on an aluminum tripod, the 4.20 kg (9.26 lbs) OTA ensures steady polar tracking.
Key Features of Skywatcher N 130/900 Explorer EQ-2 Telescope
Built for high-contrast planetary viewing, lunar mapping, and entry-level equatorial stargazing, this 130mm Sky-Watcher Explorer Black Diamond telescope pairs an f/6.9 optical layout with an EQ-2 mount. Its dual flexible slow-motion controls and 2x Barlow lens deliver sharp visual performance across solar system targets.
- 130mm (5.12 in) clear aperture with 900mm focal length and balanced f/6.9 optical speed
- Spherical primary mirror crafted from low-expansion borosilicate optical glass
- 94% reflective aluminum optical coatings with protective silicon dioxide overcoat
- Minimal 24% secondary mirror obstruction by diameter (31mm minor axis, 5.8% by area)
- 1.25-inch single-speed rack-and-pinion focuser for dependable focus adjustments
- EQ-2 manual German equatorial mount with counterbalance weight and accessory tray
- Dual flexible slow-motion control cables for smooth manual celestial tracking
- 5×24 optical finderscope, 2x Barlow lens, and Super 25mm and 10mm eyepieces included
Long-Focus Newtonian Optics & Low Central Obstruction
The elongated 900mm focal length restricts secondary mirror obstruction to just 24% by diameter, maximizing visual contrast on fine lunar rilles and planetary disks. Supported by a 1.25-inch focuser, this Sky-Watcher reflector supports visual magnifications from 18.6x up to 260x.
EQ-2 Equatorial Mount & Dual Slow-Motion Cables
Following celestial targets at high magnification requires polar alignment tracking. The Sky-Watcher Explorer 130 EQ-2 features an equatorial mount head equipped with dual flexible slow-motion control cables that allow stargazers to follow objects along right ascension smoothly. Paired with an aluminum tripod and counterweight, it provides a stable platform for planetary observation.
- EQ-2 manual German equatorial mount with counterweight for smooth polar tracking
- Dual flexible slow-motion cables for micro-adjustments along celestial coordinates
- Included 2x Barlow lens doubling visual magnification across both included eyepieces
Sky-Watcher Explorer Black Diamond Warranty
The Skywatcher N 130/900 Explorer EQ-2 Telescope is backed by a 2-year limited warranty against material and manufacturing defects. The complete factory package contains the 130mm Newtonian OTA, EQ-2 equatorial mount head, aluminum tripod with tray, counterweights, 5×24 finderscope, Super 25mm and 10mm eyepieces, and a 2x Barlow lens.
