Product Information
Full details
The Sky-Watcher Explorer-130M Telescope is designed for amateur astronomers seeking a motorized Newtonian reflector with a good balance of aperture and portability. Its key benefit is providing 30% more light gathering than a 114mm telescope, leading to brighter and more detailed views of celestial objects. A potential caveat is the learning curve associated with equatorial mounts for beginners.

FAQs
What is the primary benefit of the 130mm aperture over smaller telescopes?
The 130mm aperture gathers 30% more light than a 114mm telescope, resulting in brighter and more detailed views of fainter celestial objects like nebulae and galaxies, as well as more distinct features on planets.
Is this telescope good for beginners?
Yes, the motorized equatorial mount assists in tracking, which is a significant advantage for beginners. However, there is a learning curve associated with aligning and using an equatorial mount effectively.
What kind of objects can I see with this telescope?
You can observe the Moon's craters, the rings of Saturn, Jupiter's cloud bands and moons, Mars' polar caps (under good conditions), brighter nebulae, and galaxies.
Do I need to buy additional eyepieces?
The telescope comes with two Super Plössl eyepieces (10mm and 25mm) and a 2x Barlow lens, offering a good range of magnifications to start with. Depending on your observing interests, you might consider adding more specialized eyepieces later.
How do I maintain the telescope's mirrors?
The mirrors will require occasional cleaning and alignment (collimation). Gentle dusting with a soft brush or compressed air is recommended for routine cleaning. Collimation kits and guides are available for periodic mirror adjustment.
Can I use this telescope for astrophotography?
While the motorized mount aids tracking, it's primarily designed for visual observation. Basic astrophotography of the Moon and bright planets is possible. For deep-sky astrophotography, a more robust mount and additional equipment might be necessary.
Troubleshooting
Object drifts out of view quickly
Ensure the equatorial mount is properly aligned (polar aligned if possible) and that the motors are engaged and functioning.
Blurry or unfocused images
Adjust the rack and pinion focuser slowly until the image is sharp. Ensure the correct eyepiece is being used for the desired magnification and that the optics are clean.
Red dot finder not aligned with main telescope
Perform alignment during daylight on a distant, stationary object. Use the adjustment screws on the finder mount to center the distant object in the main telescope's eyepiece, then adjust the finder's red dot to match.
Telescope vibrates excessively
Ensure the tripod legs are fully extended and locked, and the mount is stable on the ground. Avoid touching the telescope during observation.
Pros and Cons
Pros
- Superior light-gathering ability for detailed celestial views.
- Motorized mount aids in tracking, reducing frustration for beginners.
- Includes essential accessories like quality eyepieces and a Barlow lens.
- Compact Newtonian design offers a good balance of performance and size.
Cons
- Equatorial mount may require an initial learning period.
- Motorized tracking is primarily for visual observation; advanced astrophotography may require upgrades.
- Reflector telescopes require occasional mirror alignment (collimation).
Setup, Compatibility & Care
Setup:
- Assemble the EQ2 equatorial mount according to the provided manual, ensuring all legs are securely extended and locked.
- Attach the telescope optical tube to the mount using the mounting plate. Ensure it is balanced.
- Install the finderscope and align it with the main telescope during daylight on a distant terrestrial object.
- Insert the desired eyepiece into the focuser.
- For night use, polar align the mount if possible for optimal tracking.
Compatibility:
- This telescope is compatible with Sky Watcher mounting plates for accessories.
- Standard 1.25-inch eyepieces can be used with the included focuser.
Care:
- Storage: Store the telescope in a cool, dry place, preferably in its original box or a dedicated case, away from direct sunlight.
- Cleaning Optics: Use a soft brush or compressed air to remove loose dust from the mirrors and lenses. For stubborn smudges, use a specialized lens cleaning solution and microfiber cloth, applying it to the cloth, not directly to the optics.
- Collimation: Periodically check and adjust the alignment of the primary and secondary mirrors (collimation) for optimal image clarity. Instructions for collimation are typically found in the telescope's manual.
