The Skywatcher Explorer 250PDS with EQ6-R PRO mount is a top-of-the-range set-up for passionate astronomers and demanding astrophotographers. Thanks to its large 254 mm mirror and ultra-precise motorized equatorial mount, this setup offers exceptional performance for visual observation and, above all, deep-sky imaging.
Powerful, scalable and designed for precision, this telescope is a benchmark in its class.
The Explorer 250PDS is equipped with a parabolic primary mirror of 254 mm, for sharp, detailed images free from spherical aberration. With a focal length of 1200 mm (f/4.7), It offers an excellent compromise between wide field of view and resolution capacity.
With 56 % more light than a 200 mm model, this telescope allows you to observe :
The version PDS (Photo Dual Speed) is specially designed for :
This makes the telescope ideally suited to capturing detailed images of the deep sky with a camera or SLR.
Visit EQ6-R PRO SynScan GoTo mount is a benchmark for astrophotography. It offers a load capacity of 20 kg, This means they can handle heavy configurations with excellent stability.
It incorporates many advanced technologies:
The GoTo SynScan system provides access to a database of over 42,000 celestial objects and automatically point the telescope with great precision.
Fast movement speed (up to 4.2°/second) and precise tracking make it ideal for long exposure imaging.
The frame rests on a 2-inch stainless steel tripod, This ensures excellent stability even under heavy loads. The mounting head incorporates a carrying handle, making it easy to move around despite its considerable weight.
The system includes two 5 kg counterweights for optimum balancing.
The pack includes :
This complete kit allows immediate use for observation and provides a solid basis for advanced astrophotography.
With a theoretical maximum magnification of x500, This telescope offers impressive performance. Its design makes it easy to add accessories such as a coma corrector, autoguider or dedicated camera.
It's an evolutionary instrument, capable of accompanying the user over the long term, from advanced visuals to expert astrophotography.
The Skywatcher Explorer 250PDS with EQ6-R PRO is a reference setup for astronomy enthusiasts looking for professional performance. Powerful, precise and scalable, it is perfectly suited to deep-sky astrophotography and detailed observations. An ideal choice for taking your astronomy to the next level.
With an open aperture of 254 mm at f/4.7 and a focal length of 1,200 mm, it is primarily an astrophotography instrument: when used with a camera, it is designed to photograph nebulae, galaxies, and clusters, offering a good balance between field of view and detail. For visual observation, it also shows the Moon, the planets, and the brightest deep-sky objects.
Included eyepiece: 28 mm. With a focal length of 1,200 mm, it provides 43× magnification. To calculate the magnification of an eyepiece, divide the telescope's focal length by the eyepiece's focal length.
It is an imposing instrument: the tube weighs about 14.4 kg and the mount about 17.3 kg.
Yes, and with care: in astrophotography, an open-aperture Newtonian telescope at f/4.7 requires precise collimation. A collimation laser simplifies the adjustment. The Sky-Watcher Collimation Guide (EN) explains the procedure.
Yes: The motorized equatorial mount tracks the movement of the sky, allowing for exposures of the Moon, the planets, and bright deep-sky objects. Its ST-4 autoguiding port then enables longer exposures.
250 mm Newtonian telescope, 9×50 finder scope, 2″ eyepiece holder with 10:1 reduction ratio and 1.25″ adapter, 28 mm LET eyepiece (2″), EQ6-R mount, 2″ stainless steel tripod with accessory plate, SynScan V5 hand controller with cable, 18 mm counterweight bar (240 mm + 180 mm), 2 x 5 kg counterweights, polar finder.
No. The Sky-Watcher EQ6-R Pro mount does not come with a power supply (only a 12-V cable is included). Power requirements: 12 V DC (11 to 16 V), 4 A. For home use, we recommend the'Pegasus Astro 12 V 10 A power supply with a 5.5 × 2.1 mm plug : regulated 12.5 V output, high current reserve, and it will later be able to power a Pegasus hub (Pocket Powerbox) for the camera and the anti-fog heating elements.
Here are a few accessories we've selected for this model, depending on your needs.
Optional motor for the dual-speed Crayford eyepiece holder. Check the actual model, axis, socket, clearance, and 12-volt power supply before installation.
Recommended diameter: 350 mm. Check the measurement and the mounting.
