Telescope 60700 Sturman

Appointment

Cheap long-focus refractor-achromatic objectives entry-level Sturman 60700 suitable for actionability the planets of the Solar system and contrast objects like the Moon's surface and binary stars. Smaller aperture of 60 mm and a prism diagonal make the device convenient for ground-based observations.

Parameters and functions

Design features and use

Buying a telescope 60700 Navigator, you get a starter set for astronomical observations. Refractor, unlike the reflecting telescope, less frequent re-collimation, little reacts to temperature changes and ensures a homogeneous image with the highest possible contrast. Of secondary chromatic, like purple halos around stars, are minimized due to the relative holes of 1/12, and a small field of view. Increases the detail of the planetary discs better different small low-contrast details.

With the 60-mm lens and eyepieces 5, 9 and 20 mm are available for investigation:

• the polar caps of Mars and lunar craters with a diameter of 8-9 km
• satellites of the planets of the Solar system
• large clusters and double stars like Mizar with a resolution of 2 arcmin.sec.
• weak stars with extremely affordable the magnitude of 11.5 m

When installing diagonal prism 45 deg. the observer receives correctly oriented (top/bottom) image and comfortable viewing high objects. Long lens in conjunction with the Barlow lens works as a lens Parvula and gives about 1.5 times smaller residual chromatism than a normal refractor-achromatic objectives.

Azimuth mount smaller and lighter than Equatorial, by design, resembles the head of an ordinary tripod and does not require special skills in guidance. Metal tripod is height adjustable and keeps the structural strength and precision balancing.

Package includes:

• prism diagonal 45°
  
• eyepieces 5mm (140x), 9 mm (78x), 20 mm (35x)
  
• lens Barlow 3x
  
• viewfinder 5x24
