Sevunscope CORE 150/900

The rigid, modular telescope, scalable and designed to last

The Sevunscope Core150 f/6 is an alternative to traditional tubes. It is intended for astronomers who are looking for a high-performance instrument, easy to transport and capable of following the evolution of their practice over the long term.

The idea behind the Core platform

Instead of enclosing the optics in a sheet-metal tube, we created an open chassis made of aeronautical-grade aluminum. This structure separates functions: the platform ensures structural rigidity, while the modules carry the optics.

What this changes in the field

Simplified transport : The telescope can be fully disassembled and stored easily. Ideal for traveling to deep-sky observing sites.

Thermal equilibrium : The open structure allows the mirrors to reach thermal balance naturally and quickly, eliminating the internal air-current effect found in 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)

We selected GSO mirrors (150 mm at f/6) for their consistency. The f/6 focal ratio is an ideal choice for taking advantage of high magnifications on the Moon and the planets.

An investment for your lifetime as an astronomer

The key strength of the Sevun system is its modularity. Your practice evolves? Your instrument does too. If you later wish to move to a 200 mm or 250 mm aperture, you keep your Core platform and simply install a new optical kit.
