The Messier 150\/750 EXOS-1 is a Newtonian reflector with a 150 mm parabolic mirror and a focal brandlength of 750 mm (f\/5) on the EXOS-1, a German equatorial mount of EQ-4 class with 7 kg carrying capacity, on a stainless steel tripod. The tube has a 2.5 inch Hexafoc eyepiece with adapters for 2 inch and 1.25 inch eyepieces and a T2 thread for a camera. In the Bresser Messier line this is the lightest 150 mm setup; the Messier 203\/1000 Hexafoc EXOS-2 has 83% more light and a heavier mount at 30.5 kg with counterweights, compared to 18.7 kg for this setup. How an equatorial mount works is described in Tripods and mounts explained<\/a>.<\/p>\n\n\n

Moon: craters, mountain ranges and the shadow line; at 29x with the 26 mm eyepiece as a whole disk; at 150x with a 5 mm eyepiece the small craters at the bottom of the large one; Jupiter: the banded clouds with color differences; the Great Red Spot and the shadow of a moon on the planet during a transit; at 100x to 150x; Saturn: the ring apart from the planet and on good nights the Cassini division in the ring; Sun: with the tube filter sunspots with core and gray edge; deep sky: the Orion Nebula with structure in the nebular wings; globular clusters like M13 that break off from the edge into loose stars; the Pleiades and the Andromedan Nebula at 29x in one image; and from a dark spot the brightest star clusters as a spot with a core. With the 26 mm eyepiece (29x) you see about 1.8 degrees of sky, more than three times the Moon; with a 2 inch wide-angle eyepiece of 30 mm that becomes more than two degrees. Nebulae and galaxies are seen in gray tones, not in color. From a city or village with street lighting, sun, the moon, planets, double stars and star clusters remain; nebulae and systems require a dark place. The highest meaningful magnification is approximately twice the opening, 300x; in practice, 150 to 200x is the limit due to the air above the Netherlands and Belgium. 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>, The Moon through a telescope<\/a> and The Orion Nebula through a telescope<\/a>.<\/p>\n\n<\/div>\n\n<\/div>\n\n\n
