Telescope Sturman HQ2 70070AZ
The use of the telescope Sturman HQ2 70070AZ
Refractor Sturman HQ2 70070AZ on a strong azimuthal mount - telescope baseline is simple to set up and manage a model for beginning Amateur astronomers. Due to the design of a tripod and a set of useful accessories the owner of a telescope will also be able to conduct ground-based observations and to take photographs of the moon and planets. The device allows to study numerous objects in the night sky and conduct a ground observation.
In a refractor aperture 70 mm can be seen:
- sun spots (with the necessary installed a sun filter)
- 8-km craters of the moon and the polar caps of Mars
- the moons of Jupiter and the rings of Saturn
double stars with angular sizes from 2” (castor in the constellation Gemini, Albireo in Cygnus, and Antares in the constellation Scorpio) and faint objects the magnitude limit of 11.7 m from the catalogues of Messier
Basic characteristics of the telescope Sturman HQ2 70070AZ
- Lens is multi-coated, the image without coma, and Central shielding
- 70 mm long-focus achromatic refractor with a relative aperture f/10
- The range of useful magnifications 10-175 times, with the basic eyepieces – 28 and 70 times
- Tubular stainless steel tripod with adjustable height 69-116 cm, diameter foot diameter of 1.27", thread ¼ inch
- Shelf for accessories
- Mount azimuth type with the mechanism of thin movements on height
- 3 times magnification with Barlow lens
- 5x24 optical finder for positioning and accurate search
- T-adapter (included) to install photographic equipment
Description of the telescope Sturman HQ2 70070AZ
The refractor is less sensitive to misalignment, errors in workmanship and little reacts to temperature changes. Device lens to compensate for astigmatism, coma and spherical aberration, a small relative hole 1:10 reduces the symptoms of residual chromatism. The multilayered enlightenment of optical elements helps to achieve improved contrast at the center of the image.
For positioning the telescope and search the stars in the sky use the optical viewfinder with inverted 180 ° image. Diagonal prism, mounted in front of the eyepiece, transfers the visible image in the mirror: maintained orientation top/bottom, left and right are reversed. It simplifies the monitoring bodies situated high above the horizon.
The device is mounted on a stable altazimuth mount with intuitive controls (like the tripod). Steel tripod maintains stability in windy weather, and dampens vibrations. The height of the legs is adjustable so that the observer was able to take a comfortable position for yourself. Thanks to the thread on the tripod is not difficult to fix as the telescope and binoculars or a camera. Using a T-adapter (included) on the tube without any problems, put SLR.
