The AstroMaster 70EQ is a refractor with a achromatic lens of 70 mm and a focal brandlength of 900 mm (f\/12.9), on a manual CG-2 German equatorial mount with adjustment circles, fine-adjustment cables on both axes and a steel tripod. It is the same tube as in the azimuthal version of the AstroMaster series, on a mount whose one axis points towards the Pole Star: you then follow the object with one cable. The long brandtip of the supplied 10 mm eyepiece already gives 90x, and the color edge of the lens remains thin. The series of this merk are side by side in the Celestron brand guide<\/a>.<\/p>\n\n\n

What do you see with the AstroMaster 70EQ?<\/h2>\n\n\n

Moon: craters, mountain ranges and the shadow line at 45x; at 90x with the 10 mm eyepiece, the central mountain peaks in large craters and the ridges along the shadow line. Jupiter: the two dark main bands and the four large moons, which change place from evening to evening. Saturn: the ring detached from the planet and the moon Titan as a faint star next to it. Double stars like Albireo with their color difference, a strong point of a long- brandfocus refractor. Deep-sky: with the 20 mm eyepiece you can see about 1 degree of sky, twice the Moon; the bright stars of the Pleiades fill the field of view; the Orion Nebula is a gray spot with the four Trapezium stars; the Andromedan system from a dark spot is a long oblong spot. Nebulae and galaxies are seen with the eye in gray tones, not in color. From a city or village with streetlights, the Moon, planets, double stars, and star clusters remain; nebulae and galaxies require a dark spot. The highest meaningful magnification is about 140x, twice the opening in mm; at 90x a planet without guidance drives through the image in one and a half to two minutes, with the cable of the straight climb holding it in the center. What you can expect per object is stated in What do you see through a telescope?<\/a>, Jupiter through a telescope<\/a>, Saturn through a telescope<\/a> and The Moon through a telescope<\/a>.<\/p>\n\n<\/div>\n\n<\/div>\n\n\n
