Compact Maksutov Cassegrain Telescope for Planetary Observation and Photography

The MK105 catadioptric astronomical telescope is a compact and convenient-to-carry option from the Observation Discovery & Exploration brand. It is suitable for observing and photographing the moon, planets, and other celestial bodies, as well as for astrophotography.

The imaging principle of the MK105 telescope is based on the reflection of light, without any dispersion, ensuring that there is no chromatic aberration in the final image. This is achieved through the use of a secondary mirror coating that employs high-inversion electrolyte technology, significantly improving the imaging contrast, particularly for objects such as planets.

The telescope's design incorporates a tapered extinction cylinder, which greatly enhances the extinction efficiency compared to traditional methods, effectively preventing stray light from interfering with the viewing experience.

The MK105's compact and matte-finished optical tube assembly (OTA) is both portable and durable, with a strong and robust metal mirror body construction. The length of the OTA, at 377mm, provides stability when mounted on an equatorial mount or tripod, thanks to the standard 75-degree mounting dovetail plate.

The telescope features a 1.25-inch interface, allowing for direct connection to various accessories, such as zenith mirrors, eyepieces, and astronomical cameras. If using a camera, a compatible adapter ring will need to be purchased separately.

The MK105 is equipped with two finderscope mounts, one for the embedded base and one for an external installation base, providing users with the flexibility to connect additional astronomical accessories as needed.

Regarding the optical specifications, the MK105 has an aperture of 105mm (4.13 inches), a focal length of 1365mm (53.74 inches), and a focal ratio of f/13. This results in a narrow field of view, making it more suitable for detailed lunar and planetary imaging, as well as observations of binary stars and globular clusters, rather than wide-field astrophotography.

The telescope's technical specifications include a resolution of 1.1 arc seconds, a limiting magnitude of 12.1, and a light-gathering power of 210x. The primary mirror features a multi-coated precision aluminum coating, ensuring high-quality optical performance.

In summary, the MK105 catadioptric astronomical telescope from the Observation Discovery & Exploration brand is a compact, portable, and capable instrument, well-suited for observing and photographing the moon, planets, and other celestial objects, with excellent imaging contrast and a durable construction.
