the \u2018alt\u2019 or altitude axis and left and right on the azimuth axis.<\/p>\n<p class=\"&quot;p6&quot;\">Because of its simplicity, the altazimuth mount is very popular for small instruments and even large reflectors like Dobsonians.<\/p>\n<p class=\"&quot;p6&quot;\">However, to follow an object in the heavens you need to guide the telescope about two axes simultaneously.<\/p>\n<p class=\"&quot;p6&quot;\">The altazimuth mount can\u2019t do this, and it can be awkward to study objects over a long period of time.<\/p>\n<p class=\"&quot;p6&quot;\">Astrophotography is hopeless for all but the shortest exposures using one of these mounts, but it is possible.<\/p>\n<p>For more info on how to do this, read our guide to <a
