Description
Explore distant galaxy filaments and conduct high-resolution planetary imaging with the Skywatcher N 304/1500 Explorer 300PDS EQ6 Pro SynScan GoTo computerized reflector telescope system. Designed with an f/4.9 focal ratio, this 305mm (12.01 in) aperture telescope features a 1500mm focal length, delivering 0.38 arcseconds Dawes resolving power and reaching magnitude 15.1 for automated deep-sky tracking.
The Skywatcher N 304/1500 Explorer 300PDS EQ6 Pro SynScan GoTo features an optimized parabolic borosilicate primary mirror with 94% reflective aluminum coatings and an oversized 70mm secondary mirror (23% obstruction by diameter). Its 1420mm steel tube includes a 2-inch dual-speed Crayford focuser with 1:10 micro-reduction. Mounted on an EQ6 Pro computerized GoTo equatorial mount with a 2-inch steel tripod and three 5.1 kg counterweights, the 19.00 kg OTA ensures rock-solid tracking.
Key Features of Skywatcher N 304/1500 Explorer 300PDS EQ6 Pro SynScan GoTo
Built for high-aperture automated visual astronomy, planetary high-resolution imaging, and deep-sky object tracking, this 12-inch Sky-Watcher Explorer 300PDS telescope pairs parabolic optics with an EQ6 Pro GoTo mount. Its 2-inch dual-speed Crayford focuser and three counterweights deliver exceptional stability during long observing runs.
- 305mm (12.01 in) clear aperture with 1500mm focal length and fast f/4.9 optical speed
- Precision parabolic primary mirror made from low-expansion borosilicate glass
- 94% reflective aluminum optical coatings with protective silicon dioxide overcoat
- Enlarged 70mm secondary mirror obstruction (23% diameter, 5.3% area) for full sensor coverage
- 2-inch dual-speed Crayford focuser with 1:10 micro-gear reduction and 1.25-inch adapter
- Extended in-focus travel providing 55mm backfocus clearance for coma correctors
- EQ6 Pro SynScan heavy-duty computerized German equatorial GoTo mount
- 2-inch steel tripod, three 5.1 kg counterweights, 9×50 finderscope, and 28mm eyepiece included
12-Inch Parabolic Optics & Full Sensor Illumination
The 305mm parabolic primary mirror gathers massive photon volume to resolve globular clusters to their cores, while the enlarged 70mm secondary mirror prevents edge vignetting across imaging sensors. Supported by an EQ6 Pro GoTo mount, this Sky-Watcher reflector supports magnifications from 43.6x up to 610x.
EQ6 Pro GoTo Mount & 2-Inch Tubular Steel Tripod
Managing a 19.00 kg optical tube during high-magnification planetary imaging requires an unyielding equatorial mount. The Sky-Watcher Explorer 300PDS features an EQ6 Pro GoTo mount with high-torque stepper motors and a SynScan V5 controller for accurate automated slewing. Supported by a 2-inch steel tripod and three counterweights, it dampens vibrations effectively.
- Heavy-duty EQ6 Pro GoTo equatorial mount with quiet stepper motor drives
- 2-inch tubular steel tripod column with three 5.1 kg counterweights for balance
- Losmandy-style 75mm dovetail bar with heavy cast-aluminum tube mounting rings
Sky-Watcher Explorer SynScan GoTo Series Warranty
The Skywatcher N 304/1500 Explorer 300PDS EQ6 Pro SynScan GoTo telescope is backed by a 2-year limited warranty against material and manufacturing defects. The complete factory package contains the 305/1500 PDS OTA, EQ6 Pro mount head, SynScan V5 controller, 2-inch steel tripod, three counterweights, 9×50 finderscope, and 28mm 2-inch LET eyepiece.
