The Skywatcher Skymax-102 OTA is a high-performance Maksutov-Cassegrain optical tube, designed to deliver detailed, high-contrast images in a compact, easily transportable format. Ideal for both novice astronomers and experienced users looking for a portable instrument, it excels particularly in planetary and lunar observation.
Thanks to its advanced optical design and long focal length, this telescope offers excellent resolution and high magnification, while remaining simple to use and install.
Featuring a 102 mm and a focal length of 1300 mm (f/12.74), The Skymax-102T is optimized for high-magnification observations. Its Maksutov-Cassegrain optical formula reduces aberrations and delivers sharp, bright, high-contrast images.
The primary and secondary mirrors are coated with the Radiant™ Aluminum Quartz (RAQ™), offering up to 94 % reflectivity for optimum light transmission and excellent durability.
With light-gathering capacity 28 % larger than a 90 mm model, This telescope allows precise observation:
Its theoretical maximum magnification of x204 makes full use of its optical capabilities.
The Skymax-102 OTA stands out for its compact design. Thanks to its closed design and long, folded focal length, it is easy to transport and store, making it an excellent choice for travelling astronomers.
It can be used on a variety of media thanks to :
This versatility means rapid installation and great flexibility of use.
The Skymax-102 is supplied with a universal smartphone adapter, It's easy to capture images of the Moon and planets. It's an excellent way to get started in astrophotography without complex equipment.
Focusing is ensured by a system of moving the primary mirror, with high precision and a wide adjustment range, suitable for different types of observation.
This telescope is ideal for :
The Skymax-102 OTA comes with a set of practical accessories:
These accessories provide magnifications of x65 and x130, perfectly suited to planetary and lunar observations.
Easy to set up, compact and powerful, the Skymax-102 is a telescope that is frequently used. It doesn't require time-consuming installation, so you can enjoy the night sky as soon as conditions are right.
It's an excellent choice for users who want a reliable, versatile and upgradeable instrument capable of accompanying them as they progress in astronomy.
The Skywatcher Skymax-102 OTA is a compact, precise and versatile optical tube. Ideal for planetary, lunar and simple astrophotography, it offers excellent image quality in a small format, making it the perfect choice for mobile and demanding astronomers.
The Moon in great detail, the planets (Jupiter’s bands, Saturn’s rings, Venus’s phases), and double stars: its long focal length naturally provides high magnification. For deep-sky observing, it is limited to the brightest clusters and objects. Its maximum useful magnification is approximately 204× (2 × the diameter in mm); in practice, atmospheric turbulence often requires staying below this limit.
Two eyepieces are included: 20 mm and 10 mm. With a focal length of 1,300 mm, they provide 65× and 130× magnification. To determine the magnification of an eyepiece, divide the telescope's focal length by the eyepiece's focal length.
Yes, it's a lightweight instrument: the tube weighs about 2 kg.
No, practically never: a Maksutov's optics are factory-adjusted and remain stable, which is one of its major advantages for beginners. To check, a star test is all it takes: point the telescope at a bright star, defocus it slightly, and the rings should be perfectly concentric.
This tube is sold separately: its photographic capabilities depend on the mount you choose. With its long focal length (1300 mm), it is primarily designed for planetary and lunar video recording on a motorized mount. The tube weighs approximately 2 kg: take this into account when considering the mount’s load capacity.
102 mm Maksutov-Cassegrain telescope, red-dot finder, 1.25″ angled mirror, 10 mm and 20 mm eyepieces, smartphone adapter.
Here are a few accessories we've selected for this model, depending on your needs.
Fits a 1.25-inch thread; adjust as needed depending on the installation.
1.25-inch filter for the camera; check the thread on the mount.
Optional, but particularly useful when the planet is low in the sky; check the setup and focus.
