[QUOTE="a33, post: 1057150, member: 332642"] Well, for a guestimated latitude of 58,00*: Modified axis elevation = 31,42* Modified declination offset angle = 7,35* So total dish elevation due south = 24,07*, without taking into account the offset angle of your dish (is it an offset?). These 'modified angles' follow the arc almost perfectly, so that finetuning after initial setup is hardly necessary (as opposed to the 'traditional angle values'). So not knowing your latitude means, that with these values you might not be perfectly on the arc. The above calculation is done for 'spherical' earth, using 'mean' earth radius, so in reality the results could be a few hundredths of degrees off. :) greetz, A33 [/QUOTE]
