The 90 mm aperture admits a lot of light into the beginners telescope and thus ensures a good resolution. In addition, 90mm aperture and 900 mm focal length result in an extremely large focal ratio (ratio of aperture to focal length) of 1 to 10 (F/10). The impressive result : a very sharp image with excellent contrast. Moon, Sun (using a Solar Filter) and planets - especially the celestial bodies in our immediate vicinity are more than worth a look through the BRESSER Messier AR 90/900 EQ30 telescope for beginners.The telescope comes with a height adjustable aluminum tripod and an equatorial EQ-30 mount - the perfect basis for your exploration of the universe
