The purpose of the telescope Sturman HQ2 40080AZ
Sturman HQ2 40080AZ - aperture refractor-achromatic objectives with relative apertures of 1:5 and a focal length of 400 mm. Telescope is designed for visual observations of planets, satellites, extended deep-sky objects and bright celestial bodies, galaxies and comets. Suitable to receive basic skills in astrophotography. Eyepiece with a focal length of 25 mm makes the telescope in the observation device suitable for search and observation of astronomical and terrestrial observations.

Features telescope Sturman HQ2 40080AZ
The refractor is less sensitive to fabrication errors and adverse factors operating (shaking, temperature fluctuations). Achromatic lens compensates for primary chromatism and spherical aberration. To enhance contrast in the eyepiece lens and lens coated multilayer anti-reflection coating.
The model is suitable for the acquisition of initial skills in astrophotography and observing the night sky. Step-by-step instruction in a clear and visual form explains how to begin the Assembly of the telescope and how to work with the viewfinder. Keep in mind that when observing the finder image is upside down.
Stable Alt-azimuth mount is arranged by type of tripod, to control the guidance and fixing the position using a special lever. Pry bar set tubular steel tripod with Shipov connection "dovetail". Pillars with a diameter of 1.27 inches is adjustable in height: minimum 82 cm, maximum 128 see
Eyepieces a 15 mm and 30 mm are useful for the demonstration of popular nebulae average brightness, of extended clusters and galaxies - a compromise between the desire to increase the field of view and high contrast image.
Nd filters will help to "mute" the glow of the moon and bright objects up to a level that is comfortable for the eyes. With color green ocular filter has a chance to improve the image contrast, since the fall of the human eye spectral sensitivity to red and blue a few suppress visible manifestations of the secondary spectrum.
Solar filter - a must have accessory to study the structure of sunspots flare fields. Remember that the observation of the Sun without sun filter lead to irreversible damage to the retina. Do not use the filter for any defects in the film.
In the cold season the heater protivirusni 80 mm to maintain a constant temperature Supervisory device above the dew point and protect the lenses from freezing / fogging.
As can be seen:
Moon, planets and satellites. With short-focus eyepieces convenient to observe the phases of mercury, the polar caps and seas of Mars during oppositions, study 6-kilometer lunar craters, the belts of Jupiter and the shadows of satellites on the disk of the planet, the Cassini gap in the rings of Saturn.
Deep-sky objects. Distinguishable weak stars up to 12 stellar magnitude, dozens of globular clusters, nebulae, and objects from the Messier catalogue, the brightest objects from the NGC catalog.
