SVBONY MK105 105mm Maksutov-Cassegrain OTA
The SVBONY MK105 is a compact 105mm Maksutov-Cassegrain optical tube designed for crisp, high-contrast lunar and planetary observation in a highly portable format. With a long 1365mm focal length and f/13 focal ratio, it excels on the Moon, planets, double stars, globular clusters and bright deep-sky targets.

Compact Maksutov Performance
The Maksutov-Cassegrain design combines a meniscus corrector plate with a folded optical path, giving long focal length performance in a short, travel-friendly optical tube. This makes the MK105 ideal for grab-and-go astronomy and airline-friendly setups.
- Excellent lunar and planetary contrast
- Long focal length in a compact OTA
- Stable internal focusing system
- Reduced stray light from conical baffling
Durable OTA + Easy Mounting
The MK105 features robust all-metal construction with a Vixen-style dovetail for compatibility with most equatorial and alt-azimuth mounts.

Dual finder bases allow flexible setup with optical finders, red-dot finders or guide accessories.
High Contrast Coatings
Dielectric secondary mirror coatings offer up to 99% reflectivity, while multi-coated optical surfaces help maximise contrast and throughput for planetary and lunar detail.

Best For
- The Moon
- Jupiter, Saturn and Mars
- Double stars
- Globular clusters
- Bright nebulae
