MK127 Maksutov-Cassegrain OTA
SVBONY MK127 Maksutov-Cassegrain OTA features a 127mm effective aperture and an f/11.8 focal ratio. Equipped with a three-element Maksutov structure, 99% high-reflectance dielectric coatings, a built-in flat-field design and additional both 2-inch and 1.25-inch eyepiece interfaces.This Maka telescope is well-suited for detailed observations,particularly when examining the surface features of planets and the craters of the Moon, revealing intricate details.
Designed with 127mm Objective Lens, this mak telescope provides clearer and brighter images of fainter celestial objects, such as nebulae and star clusters.
Exceptional image quality: maksutov cassegrain OTA's built-in flat-field design and three-element Maksutov-Cassegrain structure; this combination corrects for coma and astigmatism; ensuring pinpoint star images across the entire field of view
Achieve precise focus: with ease using Catadioptric Telescope OTA's intuitive dual-speed focus mechanism; allowing for rapid initial focusing; while the fine tuning knob enables meticulous adjustments for tack-sharp imagery
The 0.65x Focal Reducer can reducing the focal ratio of the MK127 from F11.8 to F7.8. This makes it easier to capture larger celestial targets in full within the photograph, which is highly practical for photographic composition.
Elevate your stargazing experience: with maksutov cassegrain OTA's flexible 2" and 1.25" eyepiece interfaces; providing compatibility with a wide range of eyepieces; allowing you to customize your observing setup for optimal performance
Amazing performance. Great Value.
I have a friend that bought one. Both gave rave reviews about its performance and value. I recommend also getting the finder scope for this telescope, as it makes it extremely easy to use. I can carry the mk127 outside, and be looking at Jupiter or Saturn in about one minute. Images are crisp,if you're not sure about buying this scope, watch the video on YouTube. Buy one, you won't be disappointed.

Great product !
A recommend this product. Highly quality my kids love it !
Excellent telescope, also perfect for terrestrial use.
Powerful, sufficiently bright, and extremely sharp. Excellent telescope with good basic features. Not too heavy, it is easily transportable.
Worth the price but needs accessories
Lightweight. High quality. This isn’t a plug-and-play setup. But I enjoy the challenge of fine-tuning, and I don’t expect instant gratification. Expect your entire setup (including this scope) to cost at least $100. I purchased the SVbony 1.25 Dual-Power 90-Degree Angle Lens (under $40). (Almost as good as the $144 Celestron and highly rated on astronomy forums.) The dielectric coating significantly improves clarity. I live in the city, and it eliminates a lot of glare. I’m adding each item one by one. I’m not into astrophotography, so I started with a tripod (not a mount). The tripod is sturdy, but I always struggle to find the target. I spent $209 on the SVBONY SV225 azimuth mount with a 10-kilogram load capacity and the SV225T astronomical telescope tripod. This setup can only be used while seated, but I think it's fine. The unexpected expense was worth it. I easily found the target and held it steady. The setup is very stable—no shaking or sagging. The telescope is easy to balance using its built-in adjustable mount. Some of my minor improvements: the red dot finder works well with the tripod but not with the new mount; when aiming upward, its position on the telescope is too low. (For obvious reasons, they don’t produce right-angle red dot finders.) In any case, the mount isn’t available for purchase. I put the telescope's original mount back on (sturdy metal, better than any mount I've seen), threaded the screws through thick double-sided tape (the protective paper remained intact), cut it to fit the slot, then slid it into the chamber and screwed the entire thing (the finder scope has screws inside) back onto the mount. It stays perfectly in place, and my $14 red dot finder now works perfectly. The dew shield is an interesting project. I wish I could find 20x12 hard plastic, but I couldn't. I used two sheets of 8.5 x 11.8 paper and taped them together (I wish I had used some kind of adhesive here first). I took four self-adhesive felt sheets of the same size, stuck them to the plastic, folded them in half but left a 4-inch overhang on one side. Then I wrapped it around the telescope, making sure to cover the lid (the top is slightly narrower). Just to be safe, since I didn’t follow the above suggestion to use glue, I secured it with a few strips of black vinyl tape. See the photo. It’s not pretty, but it’s not ugly either. And it works very well. Next step: I’m going to splurge on a lens. Again, I’m not a photography enthusiast, so I plan to buy a high-quality Bader zoom lens (8-32mm).
I’ll update my review as needed. So far, the telescope at this price point meets expectations. I didn’t expect to see any details beyond the moon. Since it’s summer in Florida, the planets are hidden behind clouds, so there’s not much to say about the telescope’s built-in lens. My efforts have significantly reduced light and humidity issues. I wish the clouds would clear up. Smile. As far as I know, to see details of Saturn or Jupiter, I need a zoom lens or other lenses. Please note that I am interested in planetary observation. For celestial bodies outside the solar system, I prefer to view publicly available James Webb Space Telescope data.
This is a fantastic telescope at a decent price.
I am a beginner in astronomy and bought this telescope as an upgrade for my 70mm/300mm FL refractor. I had been a bit skeptical about the reviews about this product, but I must admit that I was very impressed with the product and its performance, especially with planetary and near earth object observations. What also surprised me was the impressive capability that this telescope offers for hunting and observing deep space objects, especially nebulas, galaxies, and distant stars or star systems.
Great buy for the money!
Well made and good optically. Craters on the Moon, rings of Saturn, moons of Jupiter, double stars, currently visible comets, and even some deep sky objects can be seen.
Amazing scope!
As soon as I saw a review of this telescope on YouTube, I wanted it. The maksutov-cassegrain optical design allows for grater focal length (grater magnifications) in a smaller package. I own a couple more scopes (a 70mm refractor and a 130mm newtonian reflector), and yes, this is a 127mm aperture and this telescope really delivers. It performs flawlessly. It’s great for a grab-n-go telescope as well as for traveling.
This is a great buy!
Good scope!
Got a couple of shots last night with first light for the SVBony MK127 Rumac Maksutov. Used ay 1500mm focal length. Camera was ASI2600MC Air. Collimation seemed okay. Of interest is the Supernova in Galaxy 7331. Just to the bottom left of the Galactic core. Got the Bubble Nebula also. Slight issue with tracking for some reason.Maybe because image circle of the Mak is too small to illuminate the Guide sensor in the ASI2600 Air. I will try an external guide setup next time.
Excellent relationship between price, size and quality.
I'm very pleased with this telescope. I've been able to take some very good photographs thanks to its high definition and brightness. The photos of Jupiter and Mars were taken with a Celestron NextImaga10 camera, and the Moon with a Sony A6000, all with the primary mirror.

- A:The outer diameter of the MK127 is 145 mm.
- Q3:Will the reducer be included with the telescope package?
- A:Yes, it is included as a standard accessory.
- Q4:Is the 0.65× focal reducer sold separately?
- A:This reducer is a dedicated accessory and is not sold separately, it is not suitable for use with other brands of telescopes.
- Q5:Is the optical tube internally baffled to reduce stray light and improve contrast?
- A:Yes, the inner wall is coated with anti-reflective paint and includes a conical baffle.
- Q6:What is the maximum recommended useful magnification for this telescope?
- A:A magnification of 254x is perfectly acceptable.
