The rigid, modular telescope, scalable and designed to last
The Sevunscope CORE 200 f/5 is the ultimate versatile instrument. 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. It is a powerful instrument, simple to deploy on the transportable base of the CORE platform system.
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)
The 200 f/5 is a reference for its versatility. Its 1000 mm focal length makes it possible to reach significant magnifications for planetary observation while retaining strong brightness for deep-sky observing. Equipped with a 2" rack-and-pinion focuser (with 1.25" adapter) and a 62 mm secondary mirror, it ensures excellent field coverage for your imaging sensors.
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.
