[QUOTE="moonbase, post: 1077591, member: 178786"] [USER=410118]@antrabe[/USER] Assuming your pole is vertical in the East/West plane and that the mount sits on the pole without any sideways tilt, try this procedure for a prime focus dish: 1. Set your polar mount or H-H motor so that it is centred, ie, the mid point of its East/West rotational axis. 2. If you can measure the angle of the dish face by using a reference point on the back side of the dish, set it at 43.3 degrees. It you have a 2.0m long straight piece of wood you can hold it upright on the dish face and use a digital inclinometer on that, again 43.3 degrees. 3. Loosen the bolts that clamp the mount to the pole and rotate the entire mount around the pole until you get a signal from 5.0W. Peak the signal on 5.0W using small adjustments rotating the dish round the pole. Tighten the clamp bolts. 4. Adjust the main elevation bolt on the mount to peak the 5W signal some more. When it is at its maximum, measure the dish face elevation and take a note of the angle, you will need this in point 6 below. 5. Use the declination offset adjustment bolt to tilt the dish downward by 5.25 degrees by setting the dish face elevation to 48.55 degrees. You will lose the 5W signal. 6. Adjust the elevation bolt to raise the dish upward back to the angle that was set in point 4 above. Your 5W picture should be back at it maximum level. Yoy should now be able to track an arc.
