The Spinor 90/900 is a great lens telescope (refractor) with a lens diameter of 90 mm and a focal length of 900 mm. It allows for very advanced visual observations of planets and the Moon, showing a large amount of details on the surfaces of these objects. Therefore, it works perfectly as a "planetary spotter" - especially in urban and suburban areas - but it is also an efficient observation equipment for around nebular objects. Under good observation conditions, it can reveal about two hundred nebulae, galaxies and star clusters included in the Messier and NGC catalogs.
In addition, it works well as a strong observation telescope that can be placed on a larger balcony or terrace.
It also has a built-in eyepiece extractor with a diameter of 1.25 inches, which allows the use of any glasses made in this standard. The whole is a perfect solution for both beginners and advanced observers, guaranteeing a very competitive price.
The EQ3 parallactic assembly of the telescope is a recognized quality that guarantees high rigidity, enabling observation at high magnifications. A light and strong aluminum tripod with adjustable height is easy to carry and at the same time stable, and the shelf for accessories and a precise micromovement mechanism on the manual control scrolls complete the set.

The set includes the following accessories:
• 1.25 "spectacle lift
• Kellner glasses 25 mm (over 36x) and 10 mm (over 90x) - 1.25 '' standard
• 45 ° prismatic angle attachment

This device focuses a large amount of light. Looking directly at the sun through this device may result in partial or complete loss of vision. For observing the Sun, we recommend the safest method of eyepiece projection, i.e. projecting the image of our day star's target onto a piece of paper.
