The Vixen VMC260L : Catadioptric Maksutov-Cassegrain telescope
The Vixen VMC260L is a Maksutov-Cassegrain catadioptric telescope, designed to deliver outstanding performance in visual observation and astrophotography, for both planets and deep-sky objects. Its unique design and advanced technical features make it a versatile, high-performance instrument.
Optical characteristics
- Opening : 260 mm, allowing a large amount of light to be collected.
- Focal length : 3000 mm, for an aperture ratio of f/11.5.
- Corrective lens : Placed in front of the secondary mirror, it improves sharpness and reduces chromatic aberrations.
- Dielectric treatments : Applied to mirrors to maximize reflectivity and guarantee a bright image.
Mechanical design
- Open tube : Facilitates rapid cooling, reducing the fogging problems often encountered with closed telescopes such as Schmidt-Cassegrain.
- Weight : Approx. 12.1 kg, making it portable and compatible with mid-range equatorial mounts (EQ6, AZ-EQ6, iEQ45).
- Dimensions : Only 650 mm long, despite its long focal length.
Performance
- Planetary observation : Thanks to its long focal length and high resolution (0.45 arcsec), it excels at detailed observation of the planets, Moon and Sun (with appropriate filter).
- Deep sky : With its large aperture, it is capable of revealing subtle details in planetary nebulae, globular clusters or galaxies.
- Astrophotography : By adding an optional 0.62x focal reducer, the focal ratio is increased to f/7.1, making it possible to image larger objects while reducing exposure times.
Advantages over other designs
- Rapid cooling: The open tube avoids the long acclimatization periods required for closed systems.
- Optical versatility: better aberration correction than traditional Schmidt-Cassegrain thanks to its unique design.
- Transportability: Lighter than similar telescopes in diameter (such as a C11), it's easy to set up and move around.
Accessories included
- A carrying handle that can be used as a camera support.
- A standard dovetail rail compatible with most mounts.
- Note: The finder and flip-mirror are not included in the standard delivery.
Main applications
- Detailed visual observation of the planets and the deep sky.
- Advanced astrophotography with full-frame sensors thanks to its corrected field of view.
- Fast cooling for use in a wide range of environments.
In a nutshell
The Vixen VMC260L combines innovative optics and efficient mechanical design to deliver an exceptional observing and imaging experience. Its versatility makes it an ideal choice for advanced amateur astronomers looking for a high-performance instrument without compromising on quality.
