[QUOTE="a33, post: 1110156, member: 332642"] I would use the so-called modified motor angles, e.g. as in the chart this post: [URL='https://www.satellites.co.uk/forums/threads/polar-mount-setting-declination-angle.179015/#post-1109897']Polar Mount Setting Declination Angle[/URL] (Inbetween angles, not mentioned in the chart, can also be calculated.) That way you follow the arc better, than with the 'traditional motor angles' (such as: axis elevation = 90 - your latitude). It is always very important to check if the angle is meant against the vertical, or against the horizontal! There are several pictures on the internet that use incorrect terminology. This picture at sattv.info I think is rather good (though not the whole website is correct, I found!): [ATTACH type="full" alt="Sattv info Picture of motor setup angles elevazia_en.jpg"]135715[/ATTACH] NB1.: I usually use the term 'declination offset angle' (more precise), instead of 'declination angle'. NB2.: 'Polar axis angle' in the chart = 90 - axis elevation angle ('elevation with correction'). Does this help? Greetz, A33 [/QUOTE]
