Sevunscope Advanced 200/1000

The rigid, scalable modular telescope designed to go further

The Sevunscope Advanced 200 f/5 is the ultimate versatile instrument within an advanced mechanical platform. Combining a comfortable 200 mm aperture with a 1000 mm focal length, it offers an ideal aperture-to-focal-length ratio for both astrophotography and visual observation, while benefiting from the telescopic architecture of the Advanced system.

The idea behind the Advanced platform

Instead of enclosing the optics in a sheet-metal tube, we developed an open platform made of aeronautical-grade aluminum incorporating a telescopic mechanism. This architecture makes it possible to adjust the platform length to accommodate different focal lengths, while ensuring a high level of mechanical rigidity. The platform provides the structure, while the modules carry the optics.

What this changes in the field

Controlled transport : The telescope remains fully dismountable and transportable, while accommodating a more substantial structure linked to the telescopic mechanism. This is a deliberate compromise to benefit from a versatile and scalable platform.

Thermal equilibrium : The open structure allows the mirrors to reach thermal equilibrium naturally and quickly, eliminating the internal air currents typical of closed tubes.

Durable design : The use of aluminum combined with high-performance Nylon components (SLS 3D printing) guarantees a rigid and long-lasting instrument. Each unit is assembled and inspected by hand in our workshop. The mechanical structure is guaranteed for life.

A reliable optical system (GSO)

The 200 f/5 is a well-established reference for its versatility. Its 1000 mm focal length allows access to significant magnifications for planetary observation while maintaining high light-gathering power for deep-sky observation. Equipped with a 2" rack-and-pinion focuser (with 1.25" adapter) and a 62 mm secondary mirror, it ensures excellent field coverage for imaging sensors, while integrating into a platform capable of evolving toward longer focal lengths.

An investment for your lifetime as an astronomer

The key strength of the Sevun system lies in its modularity. As your practice evolves, so does your instrument. With the Advanced platform, you keep your mechanical base and can evolve your optical configuration toward other focal lengths or apertures, without calling your initial investment into question.
