The Calendar of Bloody A.tecs. Living in Central Mexico from the XII century to the being of the XVI century warlike A.tecs devoted much time to sciences including astronomy. For needs of agriculture A.tecs, using the knowledge received from the forecomers, developed the exact calendar system. 52 years of the moon-and-the sun cycle formed the basis of it (something like our conception of "a century"). ... A.tecs year was divided into 18 months with 20 days each. ... Mesopotamian astronomy. ...

DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ...
