The Dobson Levenhuk Ra 150N Dob Telescope is a great visual tool for observing star clusters, galaxies and nebulae. It creates a clear and crisp image around the field of view and allows you to observe hundreds of objects in the night sky, many of which can be seen in detail. Near-space objects are also well visible to Saturn. The possibilities of the telescope will appeal to demanding users, and even a novice astronomer can easily master the control.
Optical scheme based on the main parabolic mirror
The Levenhuk Ra 150N Dob telescope is a traditional Newton reflector. Inside it is a mirror with a diameter of 153 mm. Due to the parabolic shape, it does not distort the picture even at the maximum magnification. The mirror is complemented by an aluminum coating with a high reflection coefficient of 92-96%, which allows you to get a high-contrast and clear image across the field of view. Additional convenience is provided by the Crayford Focuser, allowing you to adjust the sharpness accurately and smoothly.
All necessary observations are already included. Mounting is stable, reliable and optimal for long-term observations of the night sky. The complete set of a telescope will allow to begin supervision at once. An 6x30 mm optical viewfinder is used to search for objects in the sky, and two glasses (9 mm and 25 mm) are used to study the sky. reflection 92 ~ 96%
