[QUOTE="frizzle1002000, post: 543510, member: 178591"] I'm trying to set up a dish on a polar mount for a motorised system using a superjack actuator and I'm finding great difficulty in understanding the various angles with which to establish correct elevation to point the dish on the arc to begin with. My latitude according to Dishpointer is 53.774 degrees. The declination angle is therefore 7.6 degrees. The Reflector offset angle is 22.3 degrees. I've got the dish pointing south and at it's zenith but here's the rub. According to the information sheets that came with the mount I add the reflector offset angle to the declination angle and this becomes a total of 29.9 degrees. There is an 'hour angle' pivot plate which should be set at an angle 29.9 degrees lesser than the reflector support tube which is parallel with the reflector face (I created this angle by unscrewing a nut on the declination adjustment rod and on doing so cross-threaded it, so I sure hope I don't have to touch that thing again!) The info sheets then mention placing the inclinometer back on the hour angle pivot plate and setting it to the latitude angle which I assume is 53.774 degrees. If I do this the elevation angle of the relector measured at the bottom rib is roughly 46 degrees which I presume is not correct.:-DOH2 If anyone could get me back on track I sure would appreciate it.
