Sky-Watcher SkyMax 127
A compact 127mm Maksutov-Cassegrain that punches above its weight for planetary and lunar detail.
Performance Scores
Overview
The Sky-Watcher SkyMax 127 is built around a Maksutov-Cassegrain design that trades wide-field views for sharp, high-contrast performance at longer focal lengths. With 127mm of aperture and a 1500mm focal length at f/11.8, this is a telescope optimized for the Moon, planets, and double stars rather than deep-sky objects. You will get crisp views of Saturn's rings, Jupiter's cloud bands, and lunar craters in impressive detail, though the narrow field of view and slow focal ratio make it less suited to galaxies and nebulae.
The optical tube weighs just 5.54kg, making it genuinely portable and compatible with a range of mounts via its Vixen-style dovetail. The matched primary and secondary mirrors with 94% reflectivity coatings help squeeze real performance from the aperture. A fully baffled tube keeps stray light in check, which contributes to the contrast that Maksutov designs are known for.
It comes ready to use with a 28mm 2-inch eyepiece, a 2-inch 90-degree star diagonal, and a 6x30 finderscope. At $610, it sits at a reasonable price point for the optical quality on offer, though you will want a solid mount to get the most from it.

Key Features
- The 1500mm focal length at f/11.8 delivers high magnification well suited to planetary and lunar observation
- Matched primary and secondary mirrors with 94% aluminum and quartz overcoat coatings produce sharp, high-contrast views
- At 5.54kg, the optical tube is light enough to pair with a compact alt-azimuth or equatorial mount for travel use
- The Vixen-style dovetail fits most standard mounts, and a 1/4-20 thread underneath allows mounting on photographic tripods
- A fully baffled tube reduces internal reflections, improving contrast against dark sky backgrounds
- Includes a 28mm 2-inch eyepiece, 2-inch star diagonal, and 6x30 finderscope so you can observe right out of the box
- The narrow field of view limits its usefulness for extended deep-sky objects, so consider your primary targets before buying

I started with a small 90mm Orion Mak-Cassegrain and wanted something a bit bigger. The 127mm Sky-Watcher was the perfect choice for me. It is a bit larger and heavier than the Orion, but is still much smaller than a Dobsonian. The added focal length and aperture give me a better, brighter, and shar...
I love this optical tube. I live in the suburbs of Orlando FL, so the light pollution isn't gonna let me see alot of deep sky objects. So a mak seemed like a logical choice for lunar and planetary astronomy. I did see the Orion nebula and the image was sharp. Planets and the moon are amazing and ide...
Overall I am pleased with the performance of the scope. I did a star test when I received the unit and it looked perfectly collimated. The focus knob is smooth with no play. It does a great job of splitting double stars. The Moon and Saturn were a bit more crisp and defined compared to the view in m...
