Design features of the telescope Sturman HQ2 90080EQ
Telescope Sturman HQ2 90080EQ is a long-focus refractor-achromatic objectives on Equatorial mount (German type).
Telescopes-refractor telescopes are considered to be maintenance-field optics that do not require long settings and frequent adjustment. They are characterized by fast equilibration, errors in manufacture, have a minimal impact on image quality and the operation of the telescope. Unlike reflecting telescopes (reflectors) refractors is no Central shielding in combination with multi-layered anti-reflective lens coating allows to achieve the highest possible contrast of the visible image. Watching the Moon or the rings of Saturn with Sturman HQ2 90080EQ, You will be able to get a quality bright image with high detail and contrast across the field of view.
The main disadvantage of this type of telescopes – the presence of chromatic aberration. The use of achromatic lenses can reduce the impact of chromatic aberrations on image quality.
The telescope is equipped by Equatorial mount (German type), which allows the telescope on only one axis in the process of tracking the observed object. The tripod, which is installed on the Equatorial mount, can be adjusted in height for comfortable observation. T-adapter, which is included in the kit, allows to use the telescope for astrophotography as lens SLR.
The interchangeable eyepieces (10mm and 25mm) and a 3x Barlow lens to allow you to choose the optimal magnification for observation. Viewfinder 5х24 is attached via a bracket to the tube of the telescope and greatly facilitates the hovering objects.
