[QUOTE="sjastro, post: 77619429, member: 352921"] [USER=376247]@contratodo[/USER] It is painfully obvious you are clueless as to how equatorial mounts work. Here is a primer on equatorial mounts 101. An equatorial mount moves in two axes, the RA (Right Ascension) axis and Declination axis. In [USER=315331]@Phil G[/USER] 's video in post #795 shows movement around the RA axis, which uses a RA motor to drive the mount so it completes a 360 degree rotation in 23 hrs and 56 minutes. The video also shows the polar axis was adjusted to 34 degrees corresponding to Sydney's latitude, if the mount was used at any other latitude at the same angle, the Sun would not stay aligned but exhibit a phenomenon known as declination drift which a north-south or south-north movement which cannot be corrected by the RA motor. If the Sun is moving around a stationary flat earth would you care to explain how the declination drift is insignificant at Sydney's location but can be significantly larger at any other latitude? There are no such problems for explaining declination drift for a rotating spherical earth. [/QUOTE]
