Description
Multi-coated BK7 optical glass and a low-expansion borosilicate primary mirror anchor the Skywatcher MC 127/1500 SkyMax 127T OTA high-contrast Maksutov-Cassegrain optical tube assembly. Designed with an f/11.8 focal ratio, this 127mm (5.00 in) aperture telescope features a 1500mm focal length, delivering 0.91 arcseconds Dawes resolving power and reaching magnitude 13.2 for planetary imaging and visual observation.
The Skywatcher MC 127/1500 SkyMax 127T OTA incorporates a Maksutov-Cassegrain optical system with an aluminized secondary spot and an MHTC multi-coated meniscus corrector. Its 370mm aluminum cylinder shell features an internal primary mirror micro-focusing mechanism, a 1.25-inch visual back with integrated T-2 camera threads, and a 44mm Vixen-style dovetail bar with direct 1/4-20 tripod threads. Weighing 3.45 kg (7.61 lbs), it provides portable high-focal-length planetary imaging.
Key Features of Skywatcher MC 127/1500 SkyMax 127T OTA
Built for high-contrast lunar and planetary observation, portable planetary video imaging, and terrestrial telephoto spotting, this 127mm Sky-Watcher SkyMax-127T OTA combines folded Maksutov optics with direct T-2 camera threading. Its dual 1/4-20 tripod threads deliver quick mounting across astronomy saddles and standard photographic tripods.

Folded Catadioptric Optics & T-2 Camera Threads
The folded optical design packs a 1500mm focal length into a 370mm tube body, eliminating chromatic aberration across planetary disks, lunar rilles, and terrestrial subjects. Equipped with direct T-2 camera threads on the rear visual back, this Sky-Watcher OTA supports magnifications from 18.1x up to 254x.
Integrated Vixen Dovetail & 1/4-20 Photo Threads
Universal mount compatibility makes this compact Maksutov optical tube ideal for travel astronomy. The SkyMax-127T features an integrated 44mm Vixen dovetail bar equipped with standard 1/4-20 photo tripod socket threads, enabling direct connection to astronomy equatorial mounts, alt-azimuth heads, or standard heavy-duty photography tripods without extra adapters.
- Integrated Vixen-style 44mm dovetail bar with standard 1/4-20 photo tripod ports
- Rear 1.25-inch visual back with direct T-2 external camera coupling threads
- 1.25-inch 90-degree star diagonal paired with Super 25mm and 10mm eyepieces
